The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.

The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide.

One hundred grams of ore and 100 grams of solution gave a very fine mud, hence settling was impossible. The ore slimed so badly that leaching would not work. Centrifugal separation was incomplete. The mixture of 100 grams of 100 mesh ore was placed in bottles on a board 18 inches in diameter and rotated rapidly, but the separation …
Electrolysis uses an anode that contains the impure copper that results from ore concentration. The cathode consists of pure copper, titanium or stainless steel . The electrolyte solution consists of copper sulfate, according to Science Clarified.
Copper ore is first mined, or dug, from the ground. Then, the ore is contacted with a weak acid solution to dissolve the copper mineral and extract it from the rock. Finally, this solution containing copper is purified by electrolysis. How is electrolysis used in mining? Electrolysis uses a direct electric current to create a chemical reaction.
