Identification of copper-sulfide species on the cuprite
Flotation methods for copper-oxide minerals tend to be divided into direct flotation and sulfidization flotation , , . In direct flotation, minerals are floated by direct addition of collectors and frothing reagents without activating agents or depressants during flotation. A disadvantage of direct flotation is the poor selectivity of the target minerals from the non-target minerals, and the

Flotation law of copper sulfide minerals (1) All iron-free copper minerals, such as chalcocite and covellite, are similar in floatability, and cyanide and lime have weaker inhibitory effects on them. (2) All copper minerals containing iron, such as chalcopyrite and bornite, are susceptible to inhibition by cyanide and lime in alkaline media.
