Abstract:

The collapse of the Fundão tailings dam of the Samarco mining complex in Mariana, Brazil, was the largest mining disaster in the world to date with many socio-economic and environmental impacts. Soil affected by mining tailings was severely altered with negative impacts for agriculture. We tested whether diluting mining tailings with organic soil would eliminate or at least attenuate the ecotoxic effects on plant development and performance. We cultivated radish, Raphanus sativus, in substrates containing different proportions of mining tailings and organic soil: pure tailings (T100%); 2) tail

Abstract:

ABSTRACTTailings are the final result of mining industry activities. Tailings are in the form of sludge waste produced from mining gold, copper, silver and other minerals. Tailings can potentially damage the environment and be dangerous to human life and other creatures. One effort to restore land from tailings is bioremediation technology. Biochar is a soil amendment material that can be used for environmental remediation. Utilizing meranti wood waste as biochar can reduce waste and increase economic value. Mahogany is a type of plant that is known to have potential as a phytoremediation plan

Abstract:

Tailings from metalliferous ore processing are stored in tailing-storage facilities. Fresh tailings contain high content of water, and this may contribute to the instability of the facilities. One way of depositing tailings into the facilities is to lay a layer of fresh tailings on top of previously deposited tailings and let the newly deposited tailings settle down for some time before another layer is laid. This paper utilises GeoStudio’s software packages SEEP/W, SLOPE/W, and SIGMA/W to analyse the effects of such deposition processing on the stability of a tailing dam. It is found that, ge

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.

Abstract:

We analyzed chemical composition, mineralogy, and spectral characteristics of the tailings of a hydrothermal gold mine in South Korea. We measured spectral responses of tailings to arsenic (As) and lead (Pb) concentration and developed and validated a prediction model for As and Pb in the tailings. The tailing was heavily contaminated with heavy metal elements and composed of rock forming minerals, gangue minerals and hydrothermal alteration minerals. The spectral features of the tailing were closely related to hydrothermal alteration minerals. The spectral responses associated with As and Pb

Abstract:

Tailing ponds are used to store tailings or industrial waste discharged after beneficiation. Identifying these ponds in advance can help prevent pollution incidents and reduce their harmful impacts on ecosystems. Tailing ponds are traditionally identified via manual inspection, which is time-consuming and labor-intensive. Therefore, tailing pond identification based on computer vision is of practical significance for environmental protection and safety. In the context of identifying tailings ponds in remote sensing, a significant challenge arises due to high-resolution images, which capture ex

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 amorph

Tailings collected from the tailing reservoir at Huogeqi Copper Mine, located in Inner Mongolia, China, were used in a leachate study to evaluate the acid potential, neutralization potential, and possibility for producing acid mine drainage (AMD) from the site. The speciation of Cu, Pb, and Zn contained in the tailings was also determined during the leachate study to further access the potential migration abilities of these metals. The results showed that the tailings did not produce significant AMD as the pH of the leachate ranged from 7 to 9 and decreased with time. The Cu, Pb, and Zn concen

The mineralogical characteristics of a phosphate tailing were studied, and the occurrence state, mineral types, and embedded characteristics of phosphorus in the phosphate tailings were ascertained. The results show that the main minerals in the phosphate tailings are collophane. The main gangue minerals are quartz, dolomite, calcite, a small amount of potassium feldspar, plagioclase, chlorite, etc. Monazite was found in phosphate tailings. In addition, the coarse grain size of quartz and feldspar and fine embedded particle size of calcite and dolomite are also the main factors affecting the m

Abstract:

Tailing dams are commonly used to safely store tailings without damaging the environment. Sand tailings (also called Sediment tailings) usually have a high water content and hence undergo consolidation during their placement. As the sediment tailings are usually placed above the ground water level, the degree of saturation and permeability of the sediment tailing is associated with the unsaturated condition due to the presence of negative pore-water pressure or suction. Current practices normally focus on the analyses saturated conditions. However, this consolidation process requires the flow

Liquid phase of the pulp after gravity separation and clarification in tailing dump is returned to technological cycle of HMP.
