For many years, production came from the oxidized capping of the orebody, which only required leaching and then electrowinning the copper, but by 1951 the oxidized reserves were primarily exhausted. The company then built a mill, flotation plant and smelter to treat the enormous reserves of underlying supergene copper sulfides.These secondary sulfides arise from the …
