A selective process for extracting antimony from refractory gold ore
ResultAbstract. To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of …

Antimony Mining Process
ResultAntimony ore beneficiation usually adopts gravity separation and flotation as a combined process. The specific gravity of antimony ore is much greater than that of gangue. It is separated by gravity separation to pre-enrich the low-grade ore. The antimony ore, after gravity separation, is then purified by flotation. Process …

Beneficiation of Antimony Oxide Ore: A Review
ResultNatural antimony was first discovered in 1777 by the Germans. By the 18th century, antimony was being roasted to reduce it to metal. In this process, stibnite was calcined to form an oxide, then reacted with carbon to liberate metal antimony, as follows: 2Sb2S3 + 9O2 2Sb2O3 + 6SO2↑. Sb2O 3 + 3C 2Sb + 3CO. ↑.
