     · In metal , a vast majority of metallurgical reactions are made to take place at elevated temperatures because than the ore compounds become relatively unstable, facilitating the release of the metal. This is the basis of pyrometallurgy. Pyrometallurgy deals with the methods of of metals from their ores and their refining and is based on physical and chemical changes ...

    About 80% of the world’s copper-from-ore originates in Cu-Fe-S ores, such as CuFeS2 and chalcocite Cu2S. The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu open pit mines to 1 or 2% Cu underground mines.

    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.
