 · Extracting copper from its ores. 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. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

The major producers of copper ore are Chile, USA and Australia, the vast majority of the ore coming from open pit mining. In open pit mining the layers of soil and vegetation seam are scooped away until the copper bearing ore is exposed. This is removed by blasting, the resulting ore collected and transported to the ore processing plant.

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 grade ores.
