Selective sulphidation and flotation of nickel from a ...
2013-12-1 Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with fine particle grinding and flotation.

Nickel flotation for High Talc Ores - strategicmet
2019-4-1 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.
