Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various …

Abstract. Sulphide Ni–Cu deposits occur typically in mafic and ultramafic igneous rocks and intrusions. The occurrence of minerals affects the separation efficiency of the sulphides. Coarse grained ores are often relatively easy to process, but some ores have altered in metamorphosis. Disseminated secondary minerals often require fine ...

Copper ore is generally an aggregate composed of copper sulfides or oxides and other minerals, which react with sulfuric acid to form blue-green copper sulfate. The industrial minerals of copper are: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. More than 280 kinds of copper-bearing minerals have been ...
