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...
