Antimony

Product Description

Stibnite (Sb2S3) is the predominant ore mineral of antimony. Antimony compounds help prevent skin burns, increase battery life, and refine glass used for cellphones. A surprising 83% of antimony consumed stateside is imported—mostly from China—leaving the US susceptible to supply disruption. The largest domestic antimony resource (estimated at 41,000 tonnes) is in a meso- to epithermal gold-antimony-tungsten deposit in the Yellow Pine historic mining district in central Idaho. This specimen comes from Antimony, Utah
