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) CuFeS 2 + 2.5 O 2 → Cu ° + FeO + 2 SO 2

Beneficiation is begun with crushing and wet-grinding the ore to typically 10–100μm. This ensures that the copper mineral grains are for the most part liberated from the worthless minerals. This comminution is carried out with gyratory crushers and rotary grinding mills.

Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

To remove the ore, boring machinery drills holes into the rock, and even explosives are used to break the rock apart. Globally, approximately 80% of copper production is taken from various sulfide sources.
