Phosphate Flotation Cell

Phosphate Flotation Cell

A reverse flotation process for removing alkaline earth metal carbonate impurities particularly dolomite and calcite as the cell overflow from a flotation feed reagentized with water, a carbonate collector, a phosphate depressant and a ph regulator to about 2030 solids and a ph of about 5.56.0. the phosphate concentrate is collected as the cell underflow.
