Production process The extraction of antimony from ores depends on the quality and composition of the ore Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue mineralsHow Antimony is Processed by Flotation,Antimony Production - Element Antimony, Sb, Metalloid,Antimony Production Follow @Atomistry Production Antimony ores are concentrated by flotation and gravity methods The element is extracted mostly by pyrometallurgical method which is precipitation of the fusion with iron Alternatively partially oxidized ores as well as for ores containing precious metals are subject of oxidizing roasting Extraction of Antimony - Element Antimony, Sb, Metalloid,This results in the production of a slag of low density containing sulphide of iron and sulphide of sodium, from which the crude antimony can settle fairly readily The crude product contains 94 to 95 per cent, antimony mixed with iron, sulphur, lead and arsenic This is refined by melting carefully under a flux of sodium carbonate(PDF) Antimony Production and Commodites - ResearchGate,Currently, secondary production acc ounts for about 20% of total antimony production and takes place mainly through the recycling of lead-acid car batteries a nd, to a much smaller extent,Antimony Smelting - Mineral Processing & Metallurgy,China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production The history of the antimony industry of China dates back to 1897 when the Tai Shing Co was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co was formed for theExtraction of Antimony - Element Antimony, Sb, Metalloid,This results in the production of a slag of low density containing sulphide of iron and sulphide of sodium, from which the crude antimony can settle fairly readily The crude product contains 94 to 95 per cent, antimony mixed with iron, sulphur, lead and arsenic This is refined by melting carefully under a flux of sodium carbonateHow Antimony is Processed by Flotation,The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony oreThe 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 quartz but contains, in addition, a small amount of talcIS THERE A FUTURE FOR PRODUCTION OF ANTIMONY,milling process by means of which antimony can be extracted from low-grade oxide ore The mines have been operated for the high-grade deposits -- those that contain ore that can be sorted to an antimony content of at least 30 percent”Antimony Production from Domestic Stibnite Ores via Sedef ,Several production methods can be used for antimony production such as gasification and reduction method, electrolyte method and Niederschlag Process [1, 5] Stibnite is totally oxidized at 350-400 & LQ UHYHUEHU W\SH furnaces as for gasification and reduction method and it takes 10-12 hours approximately with carbon source
