Extraction Of Copper Mining, Concentration, Smelting
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of

copper extraction and purification chemguide
The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.

From Ore to Finished Product Copper
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

metallurgy and hydrometallurgy copper Industrial
The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled (hot or cold), drawn or even formed into tubes before being sold. Wastewater treatment is extremely important in these factories.
