FLOTATION OF ZINC OXIDE ORE USING CATIONIC AND CATIONIC ...

The results revealed that the smithsonite particle surface was not sufficiently sulfidized. The optimal dosage of sodium sulfide is up to about 7500 g/Mg. At a high dosage, the adsorption of S2– ions increases with the increase of sodium sulfide, and the flotation of smithsonite is hence depressed. Marabini et al., 1984, found that the smithsonite recovery is not sensitive to the Na 2 S ...
