Production process The extraction of antimony from ores depends on the quality of the ore and composition of the ore. Most antimony is mined as the sulfide; lowergrade ores are concentrated by froth flotation, while highergrade ores are heated to 500–600 °C, the temperature at which stibnite melts and is separated from the gangue minerals.
Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. ANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Crystals burn with a blue flame when heated in air [Mellor 9:522 194647].

United States Antimony Corporation ("USAC", NYSE American "UAMY") reported on the Reynosa antimony plant, Mexican antimony production, North American antimony gold and silver production; progress at Los Juarez, BRZ zeolite operations, and the large inventory of antimony at the end of January.
In this process, antimony metal (sources include ingots, ore, and sodium antimonate) is melted in a furnace The molten metal is burned producing an antimony oxide vapor The vapors are quenched with air and then cooled in hairpin coolers Antimony oxide sublimes directly from a vapor to a . manufacturing process for antimony powder lepionniernl
Production Processes Antimony trioxide is produced from the reaction of antimony trichloride (SbCl3) with water, direct combination of metallic antimony with air or oxygen, roasting of antimony trisulfide, or alkaline hydrolysis of an antimony trihalide followed by dehydration of the hydrous oxide (HSDB, 2002; NRC, 2000). Uses
May 14, 2019· Metallic antimony was also known, but it was erroneously identified as lead upon its discovery. The earliest known description of the metal in the West was written in 1540 by Vannoccio Biringuccio. For some time, China has been the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan.
WOA1 Process for producing antimony trioxide . In a typical commercial plant using this conventional technology for production of antimony trioxide, the capital cost of scrubbing sulfur dioxide emissions can approach or even exceed two orders of magnitude more than the capital cost of the process which produces antimony trioxide.
