Antimony is rare in the Earth's crust having a (upper) crustal abundance of only 0.4 ppm (Rudnick and Gao, 2003). Antimony is found in over 100 different mineral species, typically in association with elements such as mercury, silver and gold. The principal ore mineral of antimony is stibnite (Sb 2 S 3). Figure 1.

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony …

The technology of concentration of the sulfide antimony-arsenic gold-bearing ore containing 3.6 g/tn Au, 0.3% Sb, and 0.4% As is developed. This technology implies the flotation separation of antimonite and arsenopyrite into separate products and allows them to perform in various cycles, increasing production efficiency due to a …
Antimony ore is divided into antimony oxide and sulfide, and its beneficiation methods are hand selection, gravity separation and flotation; it suits all antimony ore beneficiation. JXSC support customized antimony …
Maiden Ore Reserve – 606,000oz AuEq @ 6.0g/t AuEq; Development largely de-risked due to extensive existing surface and underground infrastructure, and established permitting; PFS robust financials (conservative commodity prices of US$2,000oz gold and US$15,000/t antimony) include: Over 600,000 AuEq oz projected production in current mine plan

The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore. Antimony production involves hydrometallurgy and pyrometallurgy, the latter being …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production.
