As can be seen from Figure 5, based on the microflo-
tation results, higher cumulative recovery of pentlandite
microflotation and selectivity index of pentlandite to liz-
ardite mineral samples are generated under acidic experi-
mental conditions.
Influence of Electrolytes
The influence of CaCl2 with different molar concentrations
on the microflotation of mineral samples are displayed in
Figure 6. With the increase of CaCl2 concentration, as can
be seen from Figure 6 (a), the cumulative recoveries of pent-
landite decreases, and as can be seen from Figure 6 (b), the
selectivity indexes decreases as well except when the CaCl2
molar concentration reaches 0.1 mol/L, the selectivity index
