The selective flotation of pentlandite from a nickel ore

The selective flotation of pentlandite from a nickel ore

Abstract. 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.

Nickel flotation for High Talc Ores

Nickel flotation for High Talc Ores

Apr 01, 2019 Flotation of low grade nickel sulfide ores into a concentrate suitable for smelting, and at acceptable nickel recovery, can be challenging. Alteration of the gangue minerals can mean talc is present in considerable quantities. Talc floats naturally and can be very difficult to depress without significant nickel losses. High talc bearing ores have often been considered untreatable.
