Most of the copper deposits worldwide are porphyry in nature and contribute 50– 60% of the total global copper production. These deposits consist of primarily copper sul‐phide minerals such as chalcopyrite (CuFeS2), chalcocite (Cu2S), bornite (Cu5FeS4) and enargite (Cu3As5S4).

The methods of separation are commonly based on the difference of physical properties between meaningful and gangue minerals. The major physical methods utilized to concentrate mineralization are carried out by (1) optical and other properties, (2) differences in density, (3) surface properties, and (4) magnetic and electrostatic properties.

For example, the average global copper grade is 0.62 w t. % (Mudd and Weng, 2012), however the smelter requires the grade to be around 30 w t. % before it will be accepted (Davenport et al., 2002). To accomplish this, the ore must be enriched by a factor of 48 to make it saleable. ... Electrostatic methods have been studied the most; 2 ...
