Abstract

The recovery of heavy minerals from oilsand tailings by flotation has been studied. The results obtained indicate that the optimum pH is in the range of 8. 3-11. 7. Pine oil was used as a frother and the optimum concentration was found to be 0. 15% (v/v) while frothing was depressed at its critical micelle concentration in the extraction cell water (0. 30% v/v). The use of starch to depress iron recovery also resulted in the depression of the heavy minerals. It is therefore suggested that iron removal be accomplished in the subsequent upgrading operations.
