Effect of solids on pulp and froth properties in flotation ...

2014-4-25  Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow. This ...

The effect of conditioning on Froth Flotation

2020-12-8  Effect of Collector Concentration and Pulp Density -Varying concentration and pulp density led to some unexpected findings. The collector used in most of the tests was found to ionise only weakly and hence the reaction rate constant was adversely affected by increasing collector doses. The partial ionisation also resulted in the total lack of
