Copper Mining and Extraction Oxide Ores
Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid.

Sulfide ores such as chalcopyrite CuFeS2 are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper.
Extracting Copper from Copper Carbonate
Extracting Copper from Copper Carbonate. In a crucible, we added copper carbonate and the total weight of both is 37.04g. After, we heated the crucible with the copper carbonate. It was easy to judge when the reaction had taken place as the colour of the substance had changed from the light green of copper carbonate to the black of copper oxide.After we observed this, we weighed the copper oxide

US3933475A Extraction of copper from copper sulfides
Copper is recovered from its sulfidic ores by a process wherein the ore is mixed and fused with at least a stoichiometric amount of a sulfide of sodium or potassium which may be prepared in situ by reacting sulfur with potassium or sodium hydroxide. The mixture is heated under vacuum in the absence of water, oxygen and CO 2 to a temperature above the melting point of the selected potassium or ...
Extracting a metal from its ore
Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCuOH2, is heated to produce copper oxide with the release of carbon dioxide.
