A metal ore is a rock that contains enough of the metal to make it worthwhile extracting. They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material. In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reduction ...

The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) 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.

Metallurgy
The ore is generally associated with rock impurities like clay, sand etc. called ' gangue or matrix'. The purification of ore means removal of gangue from the powdered ore. This process is otherwise called concentration of the ore or ore dressing. Thus, the percentage of the ore in the concentrated ore is higher than that in the original ore.
