Therefore, an effective depressant is essential for improving the floatability differences between apatite and dolomite. Due to its extensive sources and low unit cost, H 2SO 4 has been widely used as a depressant in apatite flotation.

Mechanism of calcium lignosulfonate in apatite and

2021-3-4  The results show that calcium lignosulfonate has a depressant effect on both apatite and dolomite, but the depressant effect on dolomite is stronger at the same dosage. Mechanism analysis shows that the adsorptive capacity of calcium lignosulfonate on dolomite is higher than that of apatite, which is due to the strong reaction between calcium lignosulfonate and the Ca sites on dolomite.

Single and mixed mineral flotation behavior and the mechanisms for the loss of selectivity in 1:1 and 95:5 apatite:dolomite mineral mixtures are presented. Loss of selectivity in mixed mineral systems is attributed to depletion of oleate ions available for adsorption by bulk precipitation with calcium and magnesium ions dissolved from dolomite.Flotation after two-stage conditioning was found
