BBC GCSE Bitesize Extraction and purification of

When it is economically feasible a mine may extract both types of copper minerals when it is not possible mines will only process either the copper oxides or This lesson will talk about extraction of some metals like aluminium copper zinc and iron It will discuss some processes like electrolysis Copper can be extracted from its ore by heating it with carbon Impure copper is purified by electrolysis in which the anode is impure copper the cathode is pure

Extracting Metals DSLV

On industrial scale copper is extracted from its sulphide ore known as copper pyrite CuFeS2 by Copper obtained by this process is called blister copperCopper is a versatile metal used in many of the products that modern civilization relies on from electronics to infrastructure For decades smelting has been the Copper can be extracted from these ores by heating them in a furnace a process called smelting The copper is then purified using a process called electrolysis
