Extraction of iron & copper: Isolation of Elements

Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

Extraction Of Coper From Its Ore

(iii) Cu2S (copper sulphide) Explaination - Copper is usually extracted from its sulphide & oxide ores. Cu2O (copper oxide) is reduced to Cu (copper) by its reaction with Cu2S (copper sulphide). 2Cu2O + Cu2S --> 6Cu + SO2. SO2 gas is formed during this reaction & have to be safely removed from the reactor. Hope this helps you.
