Arsenic USGS Mineral Resources Program

Domestic Production and Use Arsenic has not been produced in the United States since 1985, and domestic needs are satisfied by imported arsenic trioxide and arsenic metal. Arsenic trioxide is recovered from roasting arsenopyrite, the most abundant ore mineral of arsenic, as well as from copper, lead, and gold smelter flue dusts.
