Copper is one of the most important industrial metals, widely used in electrical, electronic, construction, and transportation industries due to its excellent electrical and thermal conductivity, malleability, and corrosion resistance. The chief ores of copper are primarily sulphide and oxide minerals, which vary in composition and economic importance. Among sulphide minerals, chalcopyrite (CuFeS₂) is the most significant and abundant copper ore, forming the primary source of copper extraction globally. Other important sulphide ores include bornite (Cu₅FeS₄), chalcocite (Cu₂S), and covellite (CuS). Oxide ores, which are often secondary enrichments of sulphide deposits, include malachite (Cu₂CO₃(OH)₂), azurite (Cu₃(CO₃)₂(OH)₂), and cuprite (Cu₂O), ___ ____ ___ _____ __________ _____ ___.
