mega scale extraction of copper

Extraction of Copper A way of extracting the copper from the minerals from underground was eventually discovered. It involved “roasting” the sulphide minerals in the air, which converted the elements to their oxides: CuS (s) + 2(g) CuO (s) + SO 2(g) The metal oxide can then be reduced to just the metal.

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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.

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ...
