At the plant of the New Cornelia Copper Co., the oxidized minerals are dissolved from the ore with sulfuric acid in large vats, following crushing to about 3-mesh. The solution, containing copper, together with iron, alumina and the other impurities that dissolve from the ore, is passed through towers in contact with sulfur dioxide, to reduce

Lead can be reduced from its ore galena (lead sulfide), which used to be mined in Shropshire. Copper can be reduced from malachite (copper carbonate hydroxide), which was mined in the ancient copper mines at Great Orme’s Head, Llandundo. Both ores require roasting – heating in air – before they are ready to be reduced.

The choice of copper-ore processing technology depends on its composition, i.e., the sulfide, oxide, carbonate, and copper silicate content. Leaders in copper ore processing include Chile, Peru, the United States, Australia, China, Russia, Mexico, Kazakhstan, Zambia, and Congo. Chile accounted for almost a third of global copper production in 2018.

As a result, the carbonate content of the ore often determines the processing route (i.e., leaching vs flotation). Depending on the carbonate content of the ore, acid consumption ranges from 0.4 to 0.7 tonnes H 2 SO 4 per tonne of copper recovered (Ambo, 2015, Bingöl et al., 2005).

The stepwise dissociation of cyanide from copper-cyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide''s fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

Copper ore particles formed during hydro-jet comminution are usually characterized by an isometric shape with fairly expressive edges, while their rough surface usually takes the form of highly developed spatial micro-openings for a carbonate ore (a), a multiple trimming effect for sandstone (b), or a relatively smooth surface for shale ore.

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
