Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

The effect of phase ratio on extraction of copper and cyanide with the LIX 7950 further confirmed the speculation. The extraction isotherms of copper and cyanide with the extractant were established by varying the volume ratio of the aqueous phase to the organic phase (A/O) from 2:1 to 1:8. The equilibrium pH was controlled at 10.50 ± 0.05.

Process of copper extraction. For the production of copper, so-called copper stone (Cu2S with varying contents of FeS, Cu content approx. 2%) is first obtained from chalcopyrite (CuFeS70). For this purpose, the starting material is roasted with the addition of coke and the contained iron oxides slagged by siliceous aggregates.

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.
