In this study, FeSO 4 7H 2 O was used as an auxiliary depressant to improve the selective depression effect on fluorite. Microflotation tests using oleic acid as the collector showed that the pre-addition of FeSO 4 7H 2 O and subsequent addition of sodium silicate (SS) resulted in a stronger selective depression effect on fluorite compared with SS alone.

2021-1-8 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. For example, when oleic acid is used as a collector and the pH is 8-9.5, both fluorite and calcite have better flotability.
