2019-9-26 Sulfide Ores . Virtually all sulfide-type copper ores including chalcocite (Cu 2 S) chalcopyrite (CuFeS 2) and covellite (CuS) are treated by smelting.After crushing the ore to a fine powder it is concentrated by froth flotation which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns.

This diagram shows the international trade flow in copper concentrate.The flow is from major mining countries to major industrial countries (Source: International Copper Study Group). The total trade in 2013 was over 25 million tonnes. Chile exported 8.4 million tonnes.
2015-7-26 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

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 ...
