The Thompson Nickel Belt in the Canadian province of Manitoba is estimated to contain>3 million tonnes of nickel in the form of ultramafic nickel ore [1], [2], [3]. However, processing these ores has proven difficult and uneconomical due to high serpentine (>50 wt%) and low pentlandite (<5 wt%) content [4].

In this research a procedure has been devised which rejects much of the pyrrhotite while maintaining the necessary level of talc rejection. In batch tests on an ore containing pentlandite, pyrrhotite, pyrite and talc the procedure rejected 57% of the iron sulphides and 98% of the talc and recovered 81% of the nickel in a concentrate assaying 16.5% Ni.

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.
