The selective flotation of pentlandite from a nickel ore

Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite. Concentrates have therefore been of moderate grade containing as much pyrrhotite as pentlandite or more.

Effect of feed preparation on copper activation in

In the flotation of coarse fractions, the addition of copper sulphate depressed nickel flotation without affecting gangue entrainment. However, when samples were collected directly from the plant streams and floated in a laboratory flotation cell, the addition of copper sulphate increased nickel recovery without affecting gangue entrainment in the flotation of slime, fine and coarse fractions.
