Arsenopyrite is an iron arsenic sulfide (FeAsS). It is the most abundant arsenic-bearing mineral and the primary source of arsenic metal. It is often associated with other sulfide minerals in igneous, sedimentary and metamorphic rocks. Arsenopyrite is widely distributed but is usually overlooked due to its occurrence in small amounts. Majority of the arsenopyrite occurs in hydrothermal veins. Sometimes it contains tiny particles of gold which is rarely recovered in economic quantities.

Arsenic is a toxic metal which is used in insecticides, herbicides, pesticides and chemical weapons. The dust, fumes and water containing even minor amounts of arsenic are harmful. The arsenic contamination in groundwater can occur due to the hazardous wastes or dissolution of arsenic from minerals.
