Antimony is a lustrous silvery-white material. Although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid. Among the elements found in the Earth’s crust, antimony ranks 63rd in abundance. At an average concentration of 0.20 g/t, it is less abundant than tin, arsenic or the rare earths but more abundant than bismuth, mercury or silver. Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as the free metal, usually in association with arsenic, bismuth or silver. In 2022, no marketable antimony was mined in the United States. A mine in Nevada that had extracted about 800 t of stibnite ore from 2013 through 2014 was placed on care-and-maintenance status in 2015 and had no reported production in 2022.
