Chalcopyrite Machinechalcopyrite Ore Flotation

In the paper, the flotation of a porphyry copper ore in the NovaCell is described. The head grade was 1.0 Cu , and the copper mineral was freed from encapsulation at a relatively coarse size. The initial grind size was 600 m. Tests were conducted in a laboratory unit, in both batch and continuous modes, using a conventional reagent suite.
