Arsenic Minerals Education Coalition

Most arsenic is obtained not from an ore mineral of arsenic, but as a by product in the treatment of gold, silver, copper, and other metal ores. Environmental laws require that arsenic be removed from ores, so that it does not enter the environment in effluent gases, fluids, or solids.

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.
