Arsenic Mining Processing Equipment Flow Chart Cases

2021-11-8  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. Type. Crystal System.
