Abstract:
Underground mining is the primary method to obtain economically valuable minerals, but it usually brings a large number of goafs (mined-out voids) and large quantities of waste tailings. The gradual accumulation of mine tailings has attracted worldwide attention because of its occupation and acidification of land, and a large number of goafs often lead to stope instability and ground subsidence. To solve the waste tailing accumulation and ground subsidence, a cleaner mining method—cemented tailing backfilling (CTB)—for filling mining goafs by tailings was proposed. Firstly, the volume of the goafs was detected, and the hydraulic-mechanical coupling properties of the original tailings were tested. Then, a reasonable mix proportion of tailings, binder, and water was determined based on laboratory experiments. Finally, the filling pipe network and filling system were designed according to the actual situation of the mine. This paper provides an environmental and economic method for treating tailing accumulation and preventing ground subsidence. At the same time, it was demonstrated in Linglong Gold Mine (LLGM), and a plan which allows 15.8 service years of nondischarge of tailings was designed in LLGM.

Abstract:
In order to have a comparative investigation of the pollution and speciation characteristics of heavy metals between the gold and iron mine tailings of the upstream areas of Miyun Reservoir, the tailing samples from the typical gold and iron mines were analyzed. The total metal concentration is determined by acid digestion and the chemical fractionation of metal by the Tessier sequential extraction method. It is found that compared to background values of Beijing, the heavy metal in both gold and iron mine tailings is higher, while the heavy metal in gold mine tailings is higher than that of iron mine tailings, with Mn as an exception. Mercury is the most serious pollution element in gold mine tailings. Results of the sequential extraction suggest that the exchangeable of Cd exhibits the highest percentage of total metal in gold and iron mine tailings（15% and 6.5% of the total metal, respectively) among Cd, Mn, Zn, Cu, Pb, Cr. In the majority of iron mine tailing samples collected, large amounts of Cu were mainly associated with the organic form. The percentage of the bioavailable metals in both gold and iron mine tailing samples follows the order: Cd>Mn>Zn>Cu>Pb>Cr.

Abstract:
Mine tailing disasters have occurred worldwide and contemporary release of tailings of large proportions raise concerns of the chronic impacts that trace metals may have on the aquatic biodiversity. Environmental metabarcoding (eDNA) offers an as yet poorly explored opportunity for biological monitoring of impacted aquatic ecosystems from mine tailings and contaminated sediments. eDNA has been increasingly recognized to be an effective method to detect previously unrecognized small-sized Metazoan taxa, but their ecological responses to environmental pollution has not been assessed by metabarcoding. Here, we evaluated chronic effects of trace metal contamination from sediment eDNA of the Rio Doce estuary, 1.7 years after the Samarco mine tailing disaster, which released over 40 million m3 of iron tailings in the Rio Doce river basin. We identified 123 new sequence variants environmental taxonomic units (eOTUs) of benthic taxa and an assemblage composition dominated by Nematoda, Crustacea and Platyhelminthes; typical of other estuarine ecosystems. We detected environmental filtering on the meiofaunal assemblages and multivariate analysis revealed strong influence of Fe contamination, supporting chronic impacts from mine tailing deposition in the estuary. This was in contrast to environmental filtering of meiofaunal assemblages of non-polluted estuaries. Here, we suggest that the eDNA metabarcoding technique provides an opportunity to fill up biodiversity gaps in coastal marine ecology and may become a valid method for long term monitoring studies in mine tailing disasters and estuarine ecosystems with high trace metals content.

Gold mine tailings contain extreme physical and chemical properties, which inhibit plant growth due to lower nutrition and higher heavy metal contaminants. Typha (Typha angustifolia) is type of grass growing well on waterlogged area including tailing dam. The objective of this study was to investigate the effect of arbuscular mycorrhizal fungi (AMF) in combination with compost and soil on the typha growth in gold mine tailings. The study was conducted in greenhouse by inoculating two AMF isolates (Glomus etunicatum and G. manihotis) to typha seedlings grown in pure tailing media, mixed tailing-compost media, and mixed tailing-compost-soil media. The compatibility and growth of typha grass were analysed after 1 month. Results showed that G. etunicatum and G. manihotis application significantly increased AMF colonization of typha roots up to 16.6% and 21.8% respectively. The length, number of leaves and biomass of typha also increased up to 90%, 50% and 97% respectively compared to those without AMF inoculation. G. etunicatum contributed the best growth of typha grown in mixed compost-soil-tailings, resulting in double increase of its length and biomass. The application of G. manihotis did not significantly increase the growth of typha in mixed media; however, under pure tailing, this mycorrhiza had the best induction for typha biomass and leaf number. In general, AMF application increased growth of typha grass in tailings media.

Abstract:
Mining is a primary sector for the national economy of many countries, but exploiting these natural resources causes negative impacts on the environment. Tailings produced during mining, called mine tailings, have to be disposed of, and for that purpose, they are often mixed with Portland cement to control environmental toxicity and improve their mechanical properties. However, the high environmental impacts of producing Portland cement are well known. In this sense, sustainable binders based on the alkaline activation of industrial wastes have been studied as an alternative to using Portland cement. This study focused on applying a sustainable binder based on the alkaline activation of fly ash to improve the mechanical performance of a mine tailing from a mine located in Portugal. Geotechnical tests and chemical analysis were conducted to characterize the mine tailing and fly ash used in the alkaline activation process. In addition, triaxial tests were performed to evaluate the mechanical performance of the specimens, with both natural and stabilized tailings. The developed study proved that stabilized tailing with activated fly ash shows promising mechanical performance showing that this approach can be an excellent alternative to using Portland cement.

Abstract:
ABSTRACT The microbial communities of three different sulfidic and acidic mine waste tailing dumps located in Botswana, Germany, and Sweden were quantitatively analyzed using quantitative real-time PCR (Q-PCR), fluorescence in situ hybridization (FISH), catalyzed reporter deposition-FISH (CARD-FISH), Sybr green II direct counting, and the most probable number (MPN) cultivation technique. Depth profiles of cell numbers showed that the compositions of the microbial communities are greatly different at the three sites and also strongly varied between zones of oxidized and unoxidized tailings. Maximum cell numbers of up to 109 cells g−1 dry weight were determined in the pyrite or pyrrhotite oxidation zones, whereas cell numbers in unoxidized tailings were significantly lower. Bacteria dominated over Archaea and Eukarya at all tailing sites. The acidophilic Fe(II)- and/or sulfur-oxidizing Acidithiobacillus spp. dominated over the acidophilic Fe(II)-oxidizing Leptospirillum spp. among the Bacteria at two sites. The two genera were equally abundant at the third site. The acidophilic Fe(II)- and sulfur-oxidizing Sulfobacillus spp. were generally less abundant. The acidophilic Fe(III)-reducing Acidiphilium spp. could be found at only one site. The neutrophilic Fe(III)-reducing Geobacteraceae as well as the dsrA gene of sulfate reducers were quantifiable at all three sites. FISH analysis provided reliable data only for tailing zones with high microbial activity, whereas CARD-FISH, Q-PCR, Sybr green II staining, and MPN were suitable methods for a quantitative microbial community analysis of tailings in general.

Abstract:
Improper mining waste and tailing management in Pb-Zn mining areas (Balya and Koru) in the north-west Türkiye have not been researched sufficiently. Accordingly, concentrations of heavy metal were determined in mine tailing and soils taken from Balya and Koru, and a health risk evaluation caused by heavy metals was performed. Average Cd, Cr, Cu, Mn, Ni, Pb, and Zn concentrations in mine tailings in Balya are 35.2, 17.8, 354.7, 1735, 10, 10089, 3730 mg kg-1 and these values were determined as 9.9, 8.9, 101.5, 1308, 4.5, 1871, 1375 mg kg-1 in the tailings in Koru, respectively. The concentrations of heavy metals in the soil samples taken from both Balya and Koru were determined to be lower. The evaluation of heavy metals’ health risks was performed according to both non-carcinogenic and carcinogenic effects. The primary route of heavy metals in adults and children has been determined by oral intake. For both children and adults, the order of the carcinogenic effects of heavy metals in mine tailings and soils in Balya and Koru was Cd > Pb > Ni > Cr. As the carcinogenic risk values of Cd and Pb for adults and children in mine tailing and soils in Balya were above the limit value, the children’s Cd carcinogenic risk values were found above the limit value in mine tailing and soils in Koru. The mining area in both Balya and Koru poses a risk to human health since it is close to settlements.

Abstract:
Disposal of mine tailings is one of the most important environmental issues during the mining lifetime. Especially sulphidic tailings can cause environmental and ecological risks because of their tendency to oxidize in the presence of water or air. Because of small particle size and harmful chemical properties, utilization possibilities of sulphidic mine tailings are limited. The aim of the present study was to develop technologies to utilize sulphidic mine tailings in alkali activated materials. Alkali-activated materials also known as geopolymers are nanosized zeolite type or slightly amorphous materials comparable to traditional Portland cement concrete, which can physically encapsulate or chemically stabilize the hazardous elements such as heavy metals into the 3D structure. Mine tailing based geopolymer aggregates were successfully produced from sulphidic mine tailings with good physical properties. The geopolymer aggregates performed as a concrete aggregate comparable to commercial lightweight aggregates. In addition, geopolymer mortars were prepared from mine tailings. In mortar application, there is a need to add some co-binder such as blast furnace slag in order to achieve high strength for the material. The mine tailing based geopolymer structure has an ability to stabilize a large number of cationic species into the structure while some anionic species were not able to immobilize by alkaline activation.

Abstract:
Increasing amounts of residues and waste materials coming from industrial activities in different processes have become an increasingly urgent problem for the future. The paper presents the problem of mine tailings generated in mine ?Sase? (Republic of Srpska, Bosnia and Herzegovina) with high metal content (Pb, Cu and Zn). Dumpsite of this tailing represents potential risk for water bodies in the vicinity of this location. Chosen treatment process was stabilization/solidification (S/S). Inorganic agents used in this study were fly ash and red mud that represent secondary industrial waste generated on locations relatively near the mine. Therefore, their application can be used as an example of a sustainable solution of regional environmental problem. Further investigations are related to the impact of various factors on metals leaching from mine tailings solidified/stabilized material using the above mentioned immobilization agents. The performance of the immobilizing procedures was examined using several leaching tests: ANS 16.1, TCLP, DIN, MWLP. The results indicated that all S/S samples can be considered as non-hazardous waste, as all leached metal concentrations met the set criteria. These results will further enable the modelling of metals behaviour during long-term leaching from treated mine tailing. The data are invaluable in terms of economically and environmentally sound management of mine tailing.

Abstract:
Acid mine drainage, produced from sulfur-containing mine waste exposed to air, water, and bacteria, is considered as a serious environmental pollutant because of its extremely low pH and excessive heavy metals. In order to solve the ecological environment problems caused by the acid mine drainage, treatment methods such as neutralization, adsorption, passivation, bio-inhibition, and physical coverage have been developed. Nevertheless, these methods are terminal treatment methods, which are unable to prevent the generation of acid mine drainage at the source. Recently, it is noteworthy that the tailing covering technology is particularly emphasized, owing to its superior source control capability. By reducing the contact with air, water, and bacteria, the oxidation of sulfide tailings is significantly reduced, thus avoiding the production of acid mine drainage. To date, massive research has been studied and parts of technologies have been applied, but the review on the principles, processes, and applications of these technologies are still lacking. Thus, the present review aims to increase the knowledge related to the most relevant application of tailing covering technology with the following aspects: (i) the background, concepts, and performance of tailing covering technology; (ii) the applicable conditions for each tailings coverage system and their advantages and limitations; and (iii) the future perspective of this technology.

Abstract:
Challenges to the reclamation of pyritic mine tailings arise from in-situ acid generation that severely constrains natural revegetation. While microbial communities that participate in acid generation through iron and sulfur (FeS) oxidation in acidic aquatic environments are well studied, relatively little information is available concerning the initial dynamics of in-situ soil acidification due to microbial FeS oxidation that occur in moderately acidic conditions. This research characterizes the taxonomic composition and behavior of microbial FeS oxidizing communities across a pH gradient from moderately acidic to highly acidic environmental conditions. We combine results from a 7-year compost-assisted phytostabilization field study with a controlled microcosm enrichment experiment that was conducted in an artificial soil matrix to follow the influence of pH on development of the soil microbiome. Microcosm results show that biological activity significantly increases the acidification rate in moderately acidic pH conditions in comparison to abiotic controls. Taxonomic profiles of the microbial communities in the microcosms and from the field study reveal that populations associated with both heterotrophic and lithotrophic activity (Alicyclobacillaceae, Acetobacteraceae and Xanthomonadaceae) dominate during acidification in moderately acidic conditions. These results suggest that chemoheterotrophs are an important element of the microbial community that help enable, directly and indirectly, lithotrophic FeS oxidation across moderately acidic conditions. Taken together, this research suggests that shifts of microbial populations associated with pH transitions have the potential to be used as bioindicators of the present and future status of the phytostabilization process.

Abstract:
Organic matter amendments have long been known to improve native organic matter content, aggregation and structure of soils. In the laboratory, however, organic matter amendments to autoclaved soils have no such effect. This may explain the failure of many reclamation attempts on mine tailing wastes, which often proceed without regard for the microbiological processes necessary for soil formation and cycling of plant nutrients. In this study, incubation of tailing waste with soil microbes and a simple carbon source proved sufficient to increase the formation of water stable aggregates from tailing particles. Autoclaved control samples showed no change in aggregation. The incorporation of microbial cell mass into the mineral matrix of the tailing was observed using scanning electron microscopy. These results suggest that microbial activity is necessary in order to incorporate organic matter into the abiotic matrix of tailing, promoting aggregation and ultimately soil formation from this material.

Cette étude visait à étudier la capacité d’un biodéchet calcitique seul ou en mélange avec de matériaux chimiques alcalins ainsi que l’efficacité du procédé d’électro-activation dans la neutralisation de l’acidité et le maintien de conditions alcalines dans un résidu minier sulfuré (RMS). Dans une première série d'expériences, l’évolution du pH du RMS traité avec divers amendements a été suivie en fonction de doses croissantes de coquilles d'œufs de poule (COP) ajoutées seules (2, 4, 6, 8 et 10%) ou en mélange avec 1 et 2% de ciment Portland, 1 et 2% d’oxyde de magnésium (MgO), 1 et 2% de chaux calcique et 1 et 2% de chaux dolomitique. La plus forte dose de COP (10 %) a augmenté la valeur de pH de 2,61 (sans ajout d’amendement) à 7,24. Cependant, les échantillons de RMS mélangés avec COP + ciment (1 – 2%) ou COP + MgO (1 – 2%) avaient un pH très élevé (≥ 8). Les résultats suggèrent que les composés de magnésium ou les produits calcaires riches en oxydes, en hydroxydes et en carbonates, présents dans les RMS chaulés, fournissent une protection à longue terme contre l’acidification anthropique des RMS chaulés. Dans une deuxième série d'expériences, plusieurs essais ont été effectués pour évaluer l’efficacité du procédé d’électro-activation utilisant deux compartiments, l’anode et la cathode, et certains paramètres géométriques, électriques, qualitatifs et quantitatifs, dans la neutralisation de l’acidité des suspensions de RMS introduites dans le compartiment cathodique. Tous les traitements ont influencé de façon significative les valeurs de pHcatholyte. Les résultats ont démontré que l’électro-activation permettait de neutraliser efficacement l’acidité du RMS seul ou en mélange avec COP et également d’obtenir des valeurs de pH fortement alcalines (pHcatholyte 8,0 – 10,0). En outre, l’électro-activation utilisant trois compartiments a permis d’éliminer 80% du fer ferreux d’une solution de FeSO4·7H2O.
This study aimed to investigate the capacity of a calcite biowaste alone or mixed with alkaline chemical materials and the efficiency of the electro-activation process in neutralizing acidity and maintaining alkaline conditions in a sulfide mine tailing (SMT). In a first set of experiments, chicken eggshell residue (CES) alone (2, 4, 6, 8 and 10%) or mixed with cement concrete (1 – 2%), MgO (1 – 2%), calcitic limestone (1 – 2%) or dolomitic limestone (1 – 2%) was used to neutralize sulfide mine tailing (SMT) acidity and to precipitate trace metallic elements. The highest rate of CES (10%) increased the initial tailing pH value from 2.61 (without amendment) to 7.24, indicating that CES had sufficient lime value to increase the pH of acid SMT. However, the SMT samples mixed with either CES + cement (1 – 2%) or CES + MgO (1 – 2%) had a high pH (≥ 8). The results suggested that magnesium compounds and calcareous products rich in hydroxides, oxides and carbonates present in limed SMT would provide long-term protection against acid deposition or re-acidification of limed SMT. In a second set of experiments, several trials were carried out to assess the effectiveness of electro-activation process composed by two compartments, anode and cathode, under different electric, geometrical, quantitative and qualitative parameters, in neutralizing acidity and maintaining alkaline conditions in a SMT alone or mixed with CES introduced into the cathode compartment. All treatments significantly influenced the pHcatholyte. The results demonstrated that electro-activation process is capable of neutralizing the acidity of RMS alone or mixed with COP and also to achieve alkaline pH conditions (pHcatholyte 8.0 – 10.0). In addition, the electro- activation process using three compartments can remove up to 80% of ferrous iron from an aqueous FeSO4·7H2O solution.

Abstract:
Geopolymerization has been considered as a new technology to replace the ordinary Portland cement in construction industry. It provides an option to manage the industry waste and byproducts like fly ash, mine tailings. At the same time, the CO₂ emissions can be reduced about 80% compared to that of ordinary Portland cement. The present research includes three main parts. First part is applying mine tailings as construction materials using geopolymerization method. The study is focused on efficiently activating mine tailings, reducing alkali consumption, decreasing curing time and improving compressive strength. We investigate the activation temperature effects, the impacts of additives and effects of forming pressures. The results show that a 40 MPa unconfined compressive strength (UCS) can be achieved with the geopolymerization samples after mine tailings are activated by sodium hydroxide at 170°C for 1 hour with the addition of calcium hydroxide and alkali dissolved aluminium oxide, further compressed with a 10 MPa forming pressure and finally cured at 90°C for 3 days. To elucidate the mechanism for the contribution of additives to geopolymerization, microscopic and spectroscopic techniques including scanning electron microscopy/ energy-dispersive X-ray spectroscopy (SEM/EDX), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy are used to investigate the micro/nanostructure and the elemental and phase composition of geopolymerization specimens. The stress-strain behavior was also characterized. The results shows that the mechanical behavior is similar with that of concrete and the dynamic modulus is 22 GPa, which is comparable with that of concrete. The Young's modulus of geopolymer product was also calculated and the value is in the range of 2.9 to 9.3 GPa. The findings of the present work provide a novel method for the geopolymerization of mine tailings as construction materials. Second section is applying fly ash as a high strength water-resistant construction material. Through the present investigation, a procedure has been studied. The experiment results indicate that the concentration of NaOH, water content, and curing condition can significantly affect the mechanical property of geopolymer matrix. At the same time, the chemical composition, especially the Si/Al ratio and calcium content, is also an important factor during geopolymerization. XRD results show that the amorphous feature can be observed for both high and low calcium fly ash. It is the key of the success of geopolymerizaton due to its high reactivity. XRD, FTIR and SEM tests were performed to study how experiment conditions and the properties of fly ash affect geopolymerization. The obtained compressive strength of the geopolymerization product can reach above 100 MPa. The stress-strain behavior was also characterized. The results shows that the dynamic modulus is 36.5 GPa. The product obtained from the present work shows very high water resistance without losing any compressive strength even after a one month soaking time. Third part is applying the mixture of class C fly ash and mine tailings as construction materials. Through the present investigation, a protocol has been set up. The experiment results of the present work also help set up the working conditions such as activation temperature and time, the concentration of NaOH, the addition of Ca(OH)₂, forming pressure, mine tailing to class C fly ash weight ratio, curing temperature and curing time. To elucidate the mechanism for the contribution of additives to geopolymerization, microscopic and spectroscopic techniques such as SEM/EDX, X-ray diffraction and FTIR spectroscopy were used to investigate the micro/nanostructure and the elemental and phase composition of geopolymerization composite. The obtained compressive strength of the geopolymerization product can reach above 60 MPa. The stress-strain behavior of the geopolymer matrix of the mixture of mine tailing and fly ash were also characterized and the results show that the mechanical behavior is similar to that of concrete with a 24 GPa dynamic modulus. The Young's modulus of geopolymer product was also calculated and the value is in the range of 4.0 to 13.5 GPa. The findings of the present work provide a novel method for the geopolymerization of the mixture of mine tailings and class C fly ash as construction materials, such as bricks for construction and road pavement.

A Ni(II)-dimethylglyoxime ion imprinted polymer {Ni(II)-DMG IIP} was synthesized by the trapping method using the bulk polymerisation format. The structures of the imprinted and non-imprinted polymer were evaluated by infrared spectroscopy and the morphology was observed by scanning electron microscopy. The Ni(II)-DMG IIP was optimised for pH, mass, time and by the uniform design experimental method for the molar ratios of monomer to crosslinker to porogen and template to ligands as well as keeping these parameters constant and varying the quantities of initiator, 2,2'-azobisisobutyronitrile (AIBN). The optimum pH was 8.5, optimum mass was 50 mg, optimum time was 1 min and the optimum molar ratios of crosslinker to monomer, monomer to template and nickel(II) sulfate hexahydrate (NiSO₄.6H₂O) to 4-vinylpyridine to dimethylglyoxime were found to be 3.3:1.0, 0.6:1.0 and 1.0:0.6:3.6 respectively with 30 mg and 8 mL as the optimum amounts of initiator and porogen respectively. Through this optimisation, recovery of Ni(II) was increased from 98 to 100%. Selectivity of the ion imprinted polymer was evaluated by analysing, using an inductively coupled plasma-optical emission spectrometer, for Ni(II) ions that were spiked with varying concentrations of Co(II), Cu(II), Zn(II), Pd(II), Fe(II), Ca(II), Mg(II), Na(I) and K(I) in aqueous samples. Selectivity studies also confirmed that the ion imprinted polymer had very good selectivity characterised by % RSD of less than 5 %. Co(II) was the only ion found to slightly interfere with the determination of Ni(II). The limits of detection and quantification were found to be 3x10⁻⁴ μg/mL and 9x10⁻⁴ μg/mL respectively. The method was evaluated by a custom solution of ground water certified reference material (SEP-3) and sandy soil reference material (BCR-142R) and the concentrations of Ni(II) obtained were not significantly different to the certified ones. The Ni(II)-DMG IIP was then evaluated in aqueous and soil samples where recoveries of 93 to 100% and 98 to 99% respectively were obtained with enrichment factors ranging from 2 to 18 in aqueous and 27 to 40 in soil samples. Finally, the Ni(II)-DMG IIP was used to analyse mine tailings samples and Ni(II) recovery of 99% was obtained with an enrichment factor of 2.

Abstract:
[Truncated abstract] As mineral deposits continue to be mined, the non economic gangue materials such as sulphides (e.g. pyrite) that are extracted as part of the ore body or overburden are deposited within the waste rock and/or milled tailings. As a result of natural weathering processes, these reactive materials represent a potential hazard to surrounding environments. A major consequence, resulting from mine-waste impoundments containing sulphidic materials, relates to the offsite movement of low pH leachates containing elevated concentrations of metal ions posing a contamination threat. The processes and mechanisms acting in the formation of acid mine drainage (AMD) are highly variable and, to a high extent, controlled by climatic conditions as the main driver of water flow and wetness of the system which in turn determines the availability of oxygen as well as water for pyrite weathering. In particular, this thesis is based on the hypothesis that in semiarid and arid climates the acid production may be water … The experiments were repeated at different water contents ranging from 0.24 to 0.33 cm3 cm-3. Breakthrough curves (BTC) of Li+, K+, Ca2+, Mg2+, Na+ and pH were measured and described with models of different complexities. This included the use of a simple linear and non-linear isotherms for Li+ alone, a binary Li+ - K+ ion exchange, and a complete multicomponent chemical equilibrium description of ion transport. The latter, by including dissolution of primary minerals which released base cations such as Mg2+, Ca2+ and K+ explained some of the elution patterns of base cations for which the Li+ - K+ exchange was the dominant process. Furthermore, under unsaturated water flow conditions, retardation of Li+ increased with decreasing water content. Thus solute mobility in mafic rock tailings appears to decrease under strongly unsaturated water flow conditions.

Abstract:
To a large extent, mining is a waste management business. In most mining operations, metal resources are found in host rocks at concentrations of a few percent or less, resulting in the production of large quantities of wastes during metal extraction and processing. These wastes can occur in the form of bulk waste rock, and fine-grained material (tailings) that remain after the ore is ground and processed. The two principal mine-waste management challenges are the containment of tailings, and the management of contamination leaching from tailings and waste rock. Over the past decade, several high-profile, catastrophic tailings-dam failures have led to a significant change in the way mine wastes are treated. New global standards have significantly improved industry tailing-management practices, with the potential to significantly reduce, if not eliminate, the environmental impacts of mine wastes. This essay reviews the complex problem of mine waste management, and discusses emerging new approaches—both technical and regulatory—to help ensure that mine waste storage facilities are safe from catastrophic failure, and non-polluting in perpetuity. More work is needed to ensure that these new approaches become cost-effective so that they can be widely adopted by the global mining sector.

Abstract:
Tailings in Kosovo as in any other country in the world look like an asset and mineral resources, but despite this, these Tailings have a very large impact on the process of environmental pollution. In addition to the chemical and mineralogical research of the Artana Art-1 Tailings, we have conducted research on the geostatistical distribution of most pollutants and chemical elements of this tailing. The flotation process of the Artana mine builds tailing Art-1 and the waste released from this process is dumped in this tailing (Trepca. JSC 2020). The Artana area includes the part of the territory of the Republic of Kosovo, between the coordinates 4716114, 4725406 of the northern latitude and 7530293, 7540539 of the eastern longitude. This part is mainly a mountainous area, with the Gollak Mountains in the north and the Strazha and Zhegoc Mountains in the south. Administratively the study area is part of the municipality of Prishtina. Thanks to technological processes not very advanced in these tailing, we have a high concentration of various chemical elements, this has made many researchers take this work more seriously, but in addition to the high concentration of these elements, we also have high concentration elements of As, Fe, Mn, Cu and Zn which create very large pollution in the environment.

Abstract:
Against the background of an increasingly restricted mining activity at the national level, due to the high economic costs, the active and conservation mining objectives sporadically register environmental incidents, which affects mainly the aquatic environment. Thus, in the context of excess rainfall, internal erosion processes associated with dikes and structures related to tailings ponds, poor management of the galleries under conservation can lead to the triggering of accidental pollution with mine waters and wastewaters from tailing ponds of the natural hydrographic network. The analysis of these events was done both from the perspective of spatial and temporal distribution, with a focus on the nature of involved polluting substances and the transfer of pollution waves on the local and regional hydrographic network system. The paper used information from the database of the Romanian National Water Administration, obtained as a result of the post-event investigations carried out through the Water Basin Administrations and their associated laboratories for the period 2017-2023.

Full text
Abstract:
Environmental impacts associated with the mining of carbonatite deposits are an emerging concern due to the demand for critical metals. This study investigates the chemistry of tailings seepage at the former Saint Lawrence Columbium mine near Oka, Québec, Canada, which produced pyrochlore concentrate and ferroniobium from a carbonatite-hosted Nb-REE deposit. Its objectives are to characterize the mineralogy of the tailings and their pore water and effluent chemistries. Geochemical mass balance modeling, constrained by aqueous speciation modeling and mineralogy, is then used to identify reactions controlling the chemical evolution of pore water along its flow path through the tailings impoundment. The tailings are composed mainly of REE-enriched calcite (82 wt. %), biotite (12 wt. %) and fluorapatite (4 wt. %). Minor minerals include chlorite, pyrite, sphalerite, molybdenite and unrecovered pyrochlore. Secondary minerals include gypsum, barite and strontianite. Within the unsaturated zone, pore water chemistry is controlled by sulfide oxidation and calcite dissolution with acid neutralization. With increasing depth below the water table, pore water composition reflects gypsum dissolution followed by sulfate reduction and FeS precipitation driven by the oxidation of organic carbon in the tailings. Concomitantly, incongruent dissolution of biotite and chlorite releases K, Mg, Fe, Mn, Ba and F, forming kaolinite and Ca-smectite. Cation exchange reactions further remove Ca from solution, increasing concentrations of Na and K. Fluoride concentrations reach 23 mg/L and 8 mg/L in tailings pore water and effluent, respectively. At a pH of 8.3, Mo is highly mobile and reaches an average concentration of 83 µg/L in tailings effluent. Although U also forms mobile complexes, concentrations do not exceed 16 µg/L due to the low solubility of its pyrochlore host. Adsorption and the low solubility of pyrochlore limit concentrations of Nb to less than 49 µg/L. Cerium, from calcite dissolution, is strongly adsorbed although it reaches concentrations (unfiltered) in excess of 1 mg/L and 100 µg/L in pore water and effluent, respectively. Mine tailings from carbonatite deposits are enriched in a variety of incompatible elements with mineral hosts of varying reactivity. Some of these elements, such as F and Mo, may represent contaminants of concern because of their mobility in alkaline tailings waters.
