Nickel flotation for High Talc Ores - Strategic Met

01/04/2019  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.
