Open in new tab Download slide. Leaching of low-grade copper ore in air-lift percolators. 5.1.2 Submerged leaching. Because the oxygen supply is often inadequate and the surface ratio unfavorable, percolator leaching is not very efficient, fairly slow and series of experiments lasting 100–300Copper Price,Pure copper is usually produced from a multistage process, starting with the mining and concentrating of low-grade ores that contain copper sulfide minerals. The process is then followed by smelting and electrolytic refining in order to produce a pure copper cathode. A growing share of copper is produced from acid leaching of oxidized ores. Copper hasEconomic of Copper Processing - SlideShare,23/06/2013· Effective costs of Copper Processing The NSR is thus increased to: (per tonne of ore treated) And the mine makes a profit of (per tonne of ore treated) The Effective Production Cost (EPC) of 1 tonne of copper is thus reduced to: By-products are thus extremely important in the economic of copper production, particularly for very low-grade operation.
