Abstract:
The Chauvai Hg-Sb deposit is a striking example of combining two contrasting types of mineralization in space: mercury-antimony and gold ones. The article studies the spatial-temporal and genetic relationships of goldore and mercury-antimony mineralization based on a complex of both traditional geological and mineralogicalgeochemical methods, as well as modern instrumental methods for analyzing the mineral composition. Two types of ores with clear structural confinedness have been found at the deposit: a) mercury-antimonic (cinnabarantimonite) ores, associated with jasperoid breccias and manifested exclusively along the tectonic contact of limestone of the Alai section and terrigenous rocks of the Tolubai Formation, and b) gold- sulphide (arsenopyritepyritic) ores, localized in slightly modified carbonate-terrigenous rocks of the Tolubai Formation, overlying the plane of tectonic contact. Ore formation occurred during the following stages: in the late diagenetic, without interruption passing into the catagenetic-hydrothermal, characterized by the formation of gold mineralization, and then in the later hydrothermal-telethermal, characterized by the development of Hg-Sb mineralization. It is established that the main carrying agent of invisible gold (“invisible gold”) in ores is framboidal and idiomorphic pyrite and, especially, its high-arsenic varieties. A set of conducted studies has shown that the gold ore and mercury-antimony mineralization is broken in time and is genetically associated with various hydrothermalmetasomatic processes, and the Chauvai deposit can be classified as a Carlin-like type.

Abstract:
The data on the geological and structural position, composition of metasomatites, ores, and gold content of antimony and mercury deposits and occurrences of the Priamursky gold-bearing area are presented. It was established that the ores of many of them contain native gold, whose concentration reaches commercial values. Some of the gold-bearing antimony and mercury deposits serve as sources of the formation of gold placers. By the composition of ores, near-ore metasomatites and samples of native gold, the analogues of these deposits and occurrences are the famous gold deposits of Yakutia - Sarylakh of the gold-antimony formation and Kyuchus of the gold-mercury formation. It is recommended to audit a number of mercury and antimony deposits and occurrences in the Priamursky province for gold. As a result, it is expected to identify deposits of gold-antimony and gold-and-mercury formation. In addition, occurrences of antimony and mercury may be indicative of the presence of gold-sulfide formation deposits in the bedrock, similar to a large deposit Mayskoye (Chukotka).

Abstract:
The developed extraction-spectrophotometric method for the determination of antimony utilizing 5-(pyridylazo)-2-monoethylaminoparacresol (PAAC) stands out for its selectivity, sensitivity, and rapidity. This method proves to be effective in the determination of antimony in various complex matrices, including model solutions of silicate rocks and ores. The robustness of the method is evident as it successfully analyzes these samples without the need for preliminary separation of accompanying elements. PAAC is chosen as the complexing agent for antimony. Its selectivity and sensitivity contribute to the precision of the method. The method involves an extraction step, likely utilizing a suitable organic solvent, to selectively extract the antimony-PAAC complex from the sample matrix. The concentration of antimony in the extracted complex is determined spectrophotometrically. This involves measuring the absorbance of the complex at a specific wavelength, typically chosen based on the characteristics of the PAAC-antimony complex. The method is validated by analyzing model solutions of silicate rocks and ores. This step assesses the applicability and accuracy of the method in samples that simulate real-world conditions. The method demonstrates a reproducibility of 2-5%, indicating its reliability and precision across multiple analyses. The developed method is recommended for the analysis of chemically complex materials such as industrial wastewater, ores, concentrates, and rocks.

Abstract:
Composition and genesis of arsenium-antimony sulfosalts of lead from the gold-bearing ores of the Berezitovoe deposit located in the eastern part of Mongol-Okhotsk orogenic belt (Upper Amur Area) were considered. Lead sulfosalts (Cu and Pb) are presented by tsugaruite, dufrenoysite, boulangerite, menehinite, bismuthic menehinite (with Bi up to 11.5 mass%), as well as minerals of jordanite-geocronite and bournonite-seligmannite series. The studies have revealed basic features of the lead sulfosalts relationship with ore and silicate minerals in different mineral association of vain ores and regularities in their composition variations. It was found that the composite arsenium-antimony sulfosalts form quasicontinuous series of solid compounds strongly differing from each other by the rate of semimetals as well as semimetals-Pb ratio in their composition. The suggestion has been made that the main typomorphic features of composition of the arsenium-antimony sulfosalts of lead from ores of the Berezitovoe deposit were determined by the specific processes of partial melting of sulfides under the high temperature metamorphism of primary polymetallic ores.

Abstract:
Orogenic antimony-gold deposits contribute significantly to the global antimony resource base. China’s orogenic antimony-gold deposits are primarily in southern Tibet. Investigations indicate that antimony combines and migrates with sulfur hydroxides in ore-forming fluids. Previous research on fluid inclusions in orogenic antimony-gold ores with sedimentary rock accommodation revealed the presence of organic inclusions, including liquid hydrocarbons, alongside common components such as CO2, H2O, CH4, and NaCl. However, the impact of liquid hydrocarbons on antimony migration and mineralization is still debatable. To investigate the transportability of antimony by liquid hydrocarbons in orogenic antimony ores, we selected n-dodecanethiol and n-dodecane as the subjects. We measured the solubility and occurrence form of antimony in these compounds at various temperatures and durations. The results indicate that after 5 and 10 days of reaction at 100 °C, the antimony concentrations in the n-dodecanethiol and n-dodecane groups were 67.44 ± 7.62 ppm, 75.15 ± 16.74 ppm, 1.40 ± 1.02 ppm, and 3.02 ± 3.09 ppm, respectively. At 150 °C for 5 and 10 days, the respective concentrations were 50.58 ± 5.39 ppm, 77.26 ± 45.20 ppm, 2.66 ± 3.08 ppm, and 2.41 ± 2.03 ppm. At 200 °C for 5 and 10 days, the corresponding concentrations were 339.76 ± 71.94 ppm, 218.97 ± 25.03 ppm and 6.53 ± 7.17 ppm, 2.27 ± 0.82 ppm (n = 3). The measured solubility of antimony in the n-dodecanethiol group increased gradually with rising temperature. The solubility of antimony in the n-dodecane group was low and notably inferior to that observed in the n-dodecanethiol group. X-ray photoelectron spectroscopy (XPS) analysis demonstrated a distinct thiol (R-SH) peak at 163.31 eV and compound peaks of antimony reacting with thiols at 162.06 and 160.87 eV. This suggests that antimony predominantly forms complexes with thiols for migration. Our findings suggest that specific liquid hydrocarbon components, predominantly thiols, can interact with antimony at metallogenic temperatures and persist in ore-forming fluids, facilitating migration and mineral enrichment. Earlier experimental studies on gold and crude oil have indicated that liquid hydrocarbons also play an essential role in the transportation and enrichment of gold during the formation of gold deposits, thus indicating that liquid hydrocarbons possess the considerable potential to act as an ore-forming fluid during orogenic antimony-gold deposit formation in southern Tibet.

Abstract:
Antimony is a common metalloid occurring in the form of Sb-sulfides and sulfosalts, in various base and noble metal deposits. It is also present in corresponding metallurgical products (concentrates) and, although antimony has been considered a penalty element in the past, recently it has gained interest due to its classification as a critical raw material (CRM) by the European Union (EU). In the frame of the present paper, representative ore samples from the main Sb-bearing deposits of Greece (Kilkis prefecture, Chalkidiki prefecture (Kassandra Mines), and Chios Isl.) have been investigated. According to optical microscopy and electron probe microanalysis (EPMA) data, the Greek ores contain stibnite (Sb2S3), boulangerite (Pb5Sb4S11), bournonite (PbCuSbS3), bertherite (FeSbS4), and valentinite (Sb2O3). Bulk analyses by inductively coupled plasma mass spectrometry (ICP-MS) confirmed, for the first time published, the presence of a significant Hg content in the Kilkis Sb-ore. Furthermore, Kassandra Mines ores are found to contain remarkable amounts of Bi, As, Sn, Tl, and Se (excluding Ag, which is a bonus element). The above findings could contribute to potential future exploration and exploitation of Sb ores in Greece.

Abstract:
The problems of extraction and processing of antimony ores are analyzed. The reagent-collector of oxide forms of antimony KCSb is described. It is used to develop operating parameters of the flotation concentration of ore at the Zhipkhosha deposit. The semi-industrial model experiments identified that KCSb is more efficient thatn other known reagents used to enrich antimony oxides. The operating technological conditions of the flotation process were optimized; the use of a collecting reagent indicates the expediency and effectiveness of its use. This fact was confirmed by technical and economic calculations, according to which the profit was up to 30 million rubles per 1 million of processed ore per year. An increase in the resulting product in the form of concentrate was 700–800 tons with 32–36% antimony content, which corresponds to the KSUF-3. This method can be used by antimony deposits containing oxide minerals (10% or more).

Abstract:
Antimoine et tungstène, deux "petits métaux" qui, à différentes périodes, eurent une importance stratégique liée à l'industrialisation et l'armement. L'antimoine, connu depuis l'Antiquité, fut exploité en France à partir du XVIe siècle mais c'est aux XIXe et XXe siècles qu'il fit l'objet d'une exploitation significative. Les applications industrielles du tungstène, plus récentes, datent de la fin du XIXe siècle. Aux XIXe et XXe siècles, plusieurs périodes présentent une convergence entre la taille des gisements, les méthodes d'exploitation et de traitement employées, la structure des entreprises et la consommation de ces métaux. Cette conjonction s'avère favorable à la prospérité, dans la période préindustrielle puis au XXe siècle, au développement des mines métropolitaines. La dispersion des compagnies et la multitude de petits gisements fut, au contraire, préjudiciable à la prospérité de cette activité. Dans les années 1960, l'implication de l'Etat dans la recherche minière, à travers le BRGM, puis les mesures de soutien à la prospection privée, aboutirent à la découverte de nouveaux gisements de métaux non-ferreux. En revanche, l'implication de l'Etat dans l'exploitation minière, à travers COFRAMINES, fut moins favorable. La gestion administrative et peu réactive s'avéra inadaptée à la versatilité du marché de ces métaux. Aujourd'hui, en France, la mine se heurte à de telles contraintes, sociales, administratives et environnementales, que la relance d'une exploitation de l'antimoine et du tungstène parait peu probable, dans les conditions économiques actuelles
Antimony and tungsten, two "small alloy metals" that both, at different periods of time, had a strategic importance, linked to industrialisation and armament. Antimony which was known in Antiquity, has been mined in France since the 16th century, but it was truly during the 19th and 20th centuries. Industrial applications of tungsten are recent, dating back to the last decade of the 19th century. During the 19th and 20th centuries, several periods present a convergence between the size of deposits, the methods used to exploit and process, the companies' structure, and the consumption of these two metals. This conjunction was favourable to the antimony mines' prosperity during the pre-industrial period then, in the 20th century, to the development of several mines. The dispersion of companies, on a multitude of small deposits, is prejudicial to the development of antimony and wolfram-rich districts like those of the Massif Central. The French State's implication, through the BRGM's actions starting in the 1960s, then by the establishment of aids towards private prospecting, was beneficial for the discovery of non-ferrous metals deposits. However, the State's decision to change from exploration to mining, through COFRAMINES, was less favourable. The administration management, sometimes burdened and slow to react, showed itself to be inadequate in a context as versatile as the antimony and tungsten market. Today the mining industry, in its whole, faces such social, administrative and environmental constraints, that the antimony and tungsten mining industry's revival, in today's economic and political situation, remains improbable

Abstract:
Gram-for-gram, antimony is about as toxic as arsenic but on a dose-for-dose basis it is less life-threatening simply because antimony salts rapidly cause violent vomiting which expels most of the toxin from the body before it can be absorbed. This curious ability of antimony to trigger the muscles of the stomach to expel its contents generally prevented antimony’s misuse as a murder weapon, but occasionally a large single dose did lead to death, as happened to Charles Bravo – see Chapter 10. The fatal dose can be as little as 120 mg, so long as the body retains it. Alternatively, it was possible to kill someone by giving them many small doses, which was George Chapman’s way, as we shall discover in Chapter 11. Antimony is not as widespread in nature as arsenic. It occurs to the extent of only 0.3 ppm of the Earth’s crust, and only 0.3 ppb in seawater, values which are a tenth of those of arsenic. Consequently, the amount of antimony that gets into the food chain is correspondingly less. The amount of antimony released to the atmosphere each year is about 1600 tonnes, most coming from the burning of coal, which contains 3 ppm on average, with metal smelters and municipal incinerators also releasing significant amounts. Over the centuries the amount of antimony in the environment has increased, mainly in line with lead and copper production, whose ores often contain it as an impurity. While the release of this element is of some concern the impact of antimony may have been underestimated. Professor William Shotyk of the University of Heidelberg, Germany, is an authority on antimony and his researches on peat samples taken from Swiss and Scottish bogs show that the level of antimony today is up to a thousand times higher than it was 5000 years ago. Like lead, antimony has no biological role and indeed it is ten times more toxic, and like lead it is a cumulative poison. In Chapter 5, we saw how arsenic can pass through the gut wall into the bloodstream and it can substitute for phosphate in metabolic processes, but this is not possible for antimony despite the fact that it resembles arsenic chemically.

Abstract:
The belief that there were no more than seven metals persisted for hundreds of years, and it was not until the seventeenth century that the inconvenient, inescapable realization came that there were probably many more. I’ve already mentioned Barba’s report from 1640 about the new metal bismuth; it was one of a number of metals or metal-like species that began to be noticed in the sixteenth and seventeenth centuries. In his History of Metals from 1671, Webster begins Chapter 27: ‘Having now ended our Collections and Discourse of the seven Metals, vulgarly accounted so; we now come to some others, that many do also repute for Metals; and if they be not so, at least they are semi-Metals, and some of them accounted new Metals or Minerals, of that sort that were not known to the Ancients.’ In the chapter Webster speaks of antimony, arsenic, bismuth, cobalt, and zinc. While we now understand these as distinct elements, earlier on there was great confusion, with the names being used for compounds rather than the elements themselves—and, furthermore, the different compounds and elements often being mistaken for each other. This makes unravelling their history all the more complicated. We’ll start with Barba’s ‘Mettal between Tin and Lead, and yet distinct from them both’: bismuth. The first mention of bismuth predates Barba’s reference by more than one hundred years. The name appears in its variant spelling, ‘wissmad’, in what is probably the very first book on mining geology. This was published around the turn of the sixteenth century and attributed to one Ulrich Rülein von Calw, the son of a miller who entered the University of Leipzig in 1485. Ulrich mentions in passing that bismuth ore can be an aid to finding silver, since the latter is often found beneath it. Consequently, miners called bismuth ‘the roof of silver’. As Webster later put it in his History of Metals, ‘The ore from whence it is drawn . . . is also more black, and of a leaden colour, which sometimes containeth Silver in it, from whence in the places where it is digged up, they gather that Silver is underneath, and the Miners call it the Cooping, or Covering of Silver.’

Abstract:
The Trans-Baikal Territory territory has numerous deposits and ore occurrences of arsenic, gold, antimony. The most favorable conditions for the migration and accumulation of arsenic in groundwater are created in the zone of hypergenesis of gold-antimony and gold ore deposits, confined to chemically weakly active terrigenous rocks. In the region there is a significant technogenic component of water pollution by arsenic, due to the activities of the mining industry. In the enrichment of ores of tin, gold and other deposits with high arsenic content, the main amount of arsenic (up to 80 % and more) ends up in wastes. Excess of hygienic standards of levels of element in drinking water at the level from 0,02 to 0,4 mg/1 was observed in the territories of Nerchinsky, Sretensky, Baleisky and Priargunsky districts. When assessing the health risk, it was found that the level of individual carcinogenic risk is assessed as unacceptable for the population, with regard to non-carcinogenic risk a significant excess of the allowable value of the hazard coefficient was revealed.
