copper extraction and purification

The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

Copper Smelting Chemistry Tutorial

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis ( electrowinning ) for low grade ores, or by the carbon reduction method of smelting for higher

Oxide ores cannot be reduced by carbon. Why?

All the oxides ore can be reduced by Carbon if temperature is sufficiently high because carbon act as good reducing agent at high temperature.Carbon reduction is done for many metallic oxides like ZnO PbO SnO2 etc but in case of Al2O3 Carbon reduction is not done because it will require very high temp as Al2O3 is very stable oxide and lie below in Ellingham diagram and at that temperatures carbides
