Apr 25 2014 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 overflowAn Introduction to Froth Flotation Note At a given desired pulp density and reagent combination a certain flotation contact period residence time is required to obtain the desired recovery and grade It is a simple matter to make a high recovery or a low tailing if no thought is given to the nature of the concentrate produced or
