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 from the refractory gold ore with sodium …Web

Most of the works focused on antimony dissolution from high-grade sources. One example is the work of Torma and Gabra (1977), who studied the effect of the stibnite concentration (2%–14% (w/v)) in the ore on the antimony dissolution by At. ferrooxidans at pH 1.75 and 35 °C. The tests showed that the optimum concentration of antimony (1400 …Web

Heated by granitic magmatism, Sb and S were leached from the basement rocks, forming an initial Si-rich and alkaline ore-bearing fluid. Precipitation of stibnite from the fluid resulted from interacting with wall-rocks and mixing of meteoric water, coupled by releasing of stress, decreasing of temperature and lowering of the pH at higher ...Web

Stibiconite is an earthy yellow oxide formed by the weathering of stibnite. Antimony sulfide mineralization is encased within quartz veins and was formed under relatively low temperature conditions for vein mineralization. Ore-bearing quartz veins cut steeply dipped, folded, and faulted beds of the Stanley Shale (Mississippian).Web

The use of antimony continued in the Iron Age. The Urartian cemetery in Yoncatepe Kalesi in Van (Turkey) yielded antimony buttons made from sulphur-bearing antimony ore, such as stibnite [76: p.188, fig. 9]. Similar antimony and antimony–lead alloy buttons were documented as burial goods from Middle and Late Iron Age ArmeniaWeb
