The floatability of copper sulfide minerals : All minerals that do not contain iron, such as chalcopyrite and covellite, have similar floatability and the inhibitory effect of cyanide and lime on them is weak. All iron-bearing copper minerals, such as chalcopyrite and porphyry, are easily inhibited by cyanide and lime in alkaline media.
