Copper

The concentration of copper in ores averages only 0 6% and most commercial ores are sulfides especially chalcopyrite (CuFeS 2) bornite (Cu 5 FeS 4) and to a lesser extent covellite (CuS) and chalcocite (Cu 2 S) These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching

What is roasting of a sulfide ore?

To convert sulphide ores to their respective oxides the process of roasting is used( this is done because reducing sulphide directly isn't the best way to go ahead) Can copper be extracted from its sulfide ore by roasting CuS+o2=Cu+SO2 and then heating Cuo Cu=Cu+O2 Are these equations correct?
