Arsenopyrite
Arsenopyrite is the chief ore of arsenic, and the primary ores for both copper and silver include arsenic-bearing minerals. Arsenic is also typically high in ores for gold, tin, tungsten, and lead. Most rock removed during mining operations is waste rock, left behind in tailings and waste piles. In some areas of the western United States ...
