    Chalcopyrite, the main and lowest-grade copper mineral, also reacts with water and oxygen to form water-soluble iron and copper sulfates (equation 3) that can be carried downward. Below the water table, copper sulfate reacts with in situ chalcopyrite to form covellite and, with sufficient copper sulfate, to form chalcocite (equations 4 and 5).
