Copper Ore an overview ScienceDirect Topics
Beneficiation of copper ores produces concentrates consisting mostly of sulfide minerals, with small amounts of gangue oxides (Al2 O 3, CaO, MgO, and SiO 2 ). Theoretically, this material could be directly reacted to produce metallic Cu by oxidizing the sulfides to elemental copper and ferrous oxide: (5.1) (5.2) (5.3)
