Copper Flotation - Mineral Processing Metallurgy
Mar 19, 2017 Copper Flotation Process Summary. ... The concentrate can then be reground and refloated with the production of a high-grade copper concentrate together with a low- grade pyritic tailing suitable for return to the roughing circuit. This method is likely to be less costly than one involving the fine grinding of the whole ore.
