The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of …
China is a net importer of antimony metal. Currently, 86% of Australia's antimony exports are sent to China for processing. Investing in processing capacity and infrastructure for lower-grade antimony products may offer limited strategic value for the United States, as these products will still be available under China's restrictions.
FIELD: hydrometallurgy. SUBSTANCE: invention relates to the hydrometallurgy of non-ferrous metals for the processing of sulfide antimony gold-containing concentrates. The method includes sulfide-alkaline leaching of the concentrate, which is carried out in two stages in a countercurrent mode. The first stage of leaching is …

Current processing technology for antimony-bearing ores 551 Turhal antimony plant, Turkey Turhal processes a type of ore with quartz veins and stibnite as the sole ore mineral [8]. A certain amount of calcite and pyrite is present in the ore. Graphite and arsenic-bearing minerals, which are more troublesome from the point of view of …
remove antimony from ores and concentrates containing gold. The use of one or another method of processing antimony-containing ores and concentrates depends on the antimony content in them and its form of location (Table 1). Antimony metallurgy is intended for the production of metallic antimony by pyrometallurgical and …
The leaching sediment contains about 20% antimony and can be processed pyrometallurgically in the short drum furnace analogous to the As-Sb dross processing, In this way, besides the antimony and lead, the sodium present in the alkali Sb-slag is …

The common global practice of processing antimony sulphide concentrates (20–30% Sb) is based on alkaline sulphide leaching followed by precipitation of metallic antimony by electrowinning ...
During processing antimony is mobilized reporting to waste solid tailings or effluent streams. This becomes a matter of concern since antimony is similar to arsenic in many respects, both sharing similar chemical properties as well as toxicity and thus have negative environmental implications, especially in the context of industrial effluents ...

Xtra Energy Corp. is an antimony exploration company focused on developing its flagship project "American Antimony", approximately 31 miles northeast of Eastgate, Nevada.
Antimony had a similar effect to arsenic on the nickel extraction (Fig. 8), with a decrease in the rate and extent of nickel extraction as the antimony addition to the system increased (i.e. higher percentages of antimony sulphide in the concentrate mixture). Reduced leaching of aluminium from the solids and precipitation of aluminium …
United States Antimony Corporation (NYSE:UAMY) is a nano-cap company based in Thompson Falls, Montana, that owns the only antimony refining and processing facility in the United States.
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. ... During processing of sulfide concentrate, most Sb 2 S 3 is oxidized to become Sb 2 O 3, which will be volatilized.
The present research is aimed at (i) purifying impure complex copper sulphide concentrates by selectively dissolving the impurities, and consequently, upgrading the concentrates for pyrometallurgical processing, and (ii) depositing antimony as a marketable product from synthetic alkaline sulphide pregnant leach liquors by electrowinning.
