... Arsenic also occurs as a trace to minor component in pyrite, and arsenian pyrite is common in many gold deposits. Arsenic contents of gold ores in the gold-pyrite belt are expected to be in concentrations of a few hundred to perhaps a few thousand parts per million, with essentially all of the arsenic hosted in trace arsenopyrite and as a trace element in pyrite.
