Mercuryrich concentrates are also known to supplement primary stibnite supply in China, but at the current antimony prices, Roskill understands that this source has become largely unprofitable. While imports of antimonygold concentrates from Russia remain high, most conventional antimony smelting plants are unable to treat the high Au/As Russian concentrates due to high operating costs and low .
Estimates of the abundance of antimony in the Earth's crust range from to parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb2S3) is the predominant ore mineral of .
Since stibnite ore reacts slowly and incompletely with mineral acids alone, they have been used in combination with other reagents tartaric acid [6] . The reductive leaching using iron powder in mineral acid has also been reported for the efficient recovery of antimony from stibnite [7] .
In 1914, the price of antimony tripled to over 20 cents per pound, and mining and smelting operations were briefly resumed, apparently using the old Boushey smelters. This operation shipped five or six railway carloads of ore during World War I.

Stibnite (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
THE STIBNITE DISTRICT • The Stibnite Gold Project takes an area mined for over 100 years and uses modern mining capabilities and a sustainable approach to restore the environment. • Mining in the area started in 1899, for gold and the site became the primary source of tungsten and antimony during the World War II and Korean war eras. •
