Flotation Tests on Ultra-Fine Oolitic Cellophane

Abstract:

The collophane is in oolitic structure, and associates with the gangue intricately; and hence a good concentrate in performance is hardly produced only by rinsing, in order to achieve a full liberation, fine-grinding is needed for the cellophane. Based on the results of both direct and reverse flotation tests, it shows that reverse flotation is effective in the benefication of the apatite to a certain extent. When reverse flotation is used to dress the run-of-mine which contains 26.95%P₂O₅, a concentrate containing 32.69% P₂O₅ can be obtained at a recovery of 84.99%.
