Antimony. A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only a few countries, with China being its largest producer. Antimony is used for many technological and industrial purposes. Antimony is used as a hardening alloy for lead, especially ...

Antimony. Stibnite from Comadai near Bacchus Marsh, Victoria (Scale: 5 cm) When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry.

the stibnite-quartz deposits are distinctly lower than those of the gold-antimony deposits. Gold has been identified in the Lake George (New Brunswick, Canada) stibnite-quartz deposit, but it is present in a minor vein set ( Seal and others, 1988) and has not been extracted during mining and milling of the ore. Relative to simple, disseminated,

In 2022, no marketable antimony was mined in the United States. A mine in Nevada . that had extracted about 800 tons of stibnite ore from 2013 through 2014 was placed on care-and-maintenance status in 2015 and had no reported production in 2022. Primary antimony metal and oxide were produced by one company in Montana using imported feedstock.
