There is an increasing trend in the extraction and development of copper resources from complex deposits. These complex deposits pose mineral processing
Beneficiation is begun with crushing and wet-grinding the ore to typically 10–100μm. This ensures that the copper mineral grains are for the most part liberated
The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains
