• Flotation an overview | ScienceDirect Topics

    Flotation is a process widely used in the mineral processing industry to float out specific components of a slurry type mixture. Such a process clearly operates during bubble degassing of metal, although the researches so far have concentrated on the removal of gas rather than the floating out of oxides.
