Among those methods, flotation procedure, a method for mineral separation, is widely applied in smelters because of its great processing capacity as well as relatively small investment cost for equipment and reagents [ 7 ]. Most importantly, for the recovery of copper in the form of sulfide, the flotation usually possesses better effects.

Froth flotation is mainly operated under two common techniques : 1. Direct floatation technique - In this method, the mineral sticks to the air bubble and the remaining gangue settles down at the bottom. 2. Reverse floatation technique - In this method, the gangue sticks to the air bubble and ore particles settle down in the bottom.
