Arsenic Minerals Education Coalition

Arsenic. Arsenic (As) is classed as a semi metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.

Influence of Copper and Arsenic on Gold Recovery in the

The oxidized ore of Yalea has a considerable influence on the recovery rate of gold, due to the presence of secondary sulphides (covellite and chalcocite). Arsenic is more related to gold (R = 0.5) than copper (R = 0.2), and its content is higher than that of copper in the blocks.
