The ore sample used in this study is of high nickel grade (1.35%). Approximately 96% of the nickel in the ore is in the form of pentlandite and may be recovered by true flotation. The remaining 4% of nickel is distributed in non-sulphide minerals, which may only be recovered by the entrainment mechanism or as composites with pentlandite.

The flotation target was a higher nickel recovery from a concentration grade of 4% nickel and 35% iron. Sulphide ore is mainly associated with the following minerals pyrrhotite, pentlandite, chalcopyrite and pyrite. Pentlandite is the most abundant sulphide mineral and is the main nickel mineral in almost all nickel sulphide deposits [4, 5, 6].
