Flotation of sulphides ore fines and ultrafines particles

Advances In Sulphides Flotation Cell Machine. Advances in Fine and Coarse Particle Flotation Canadian. Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter for base metal ores. In this range it is possible to obtain quite high recoveries in conventional flotation machines.
