Seven Tricks to Improve The Effect of Fluorite Flotation ...

2021-1-8  When oleic acid is used as the collector and the pH is 8-11, the flotability is good, and the recovery rate of fluorite ore can reach 80%-90%. For different types of fluorite ore, the flotability of the gangue minerals is also greatly affected by the pH value, which in turn affects the flotation effect of fluorite ore.

2003-7-1  Also, fluorite flotation could be improved by using effective depressants when fatty acid is used as collector. For example, acidized sodium silicate was reported to depress calcite strongly in preference of fluorite at ambient temperature, leading the fluorite flotation to be achieved at a lower temperature (Zhou and Lu, 1992).
