Mineral Flotation Cell Using Flotation Cell Models

Working principle of flotation cell. The impeller is rotated by V-belt of motor and produces negative pressure by centrifugal function. Enough air is sucked to mix slurry, and slurry mixes drug at the same time. Mineral sticks on bubble completely and floats on the surface of slurry to form mineralized bubble. Useful bubble is scraped out by adjusting flashboard height and controlling liquid

How the various economic minerals occur in the ore i.e. in what way they are associated with each other and the various components of the host rock is determined by the ore’s geology which is measured by a mineralogist. How these associations affect recovery by flotation is measured as the ore’s flotation kinetics. The

SCHWARZ CSIRO Minerals, Clayton, Victoria 3169, AUSTRALIA ABSTRACT The effect of impeller speed on the air flow in a self-aerated Denver laboratory flotation cell was investigated using computational modelling. Air is induced into the slurry by the impeller’s rotating action. The rate of air flow is determined by the
