Talc Deslime Ahead of Flotation This is used at BHP, Nickel West at Mt Keith in Western Australia where the nickel ore contains significant talc levels. They use large banks of 50 mm polyurethane cyclones to deslime the talc from cyclone overflow ahead of the flotation feed. The cyclones cut at 2 microns and result in very little nickel being lost.
