Abstract

A cyclonic froth flotation cell, suitable for use in the separation of minerals comprises concentric inner and outer cyclones (2, 4). A liquid feed containing particles and injected dissolved air is fed tangentially via a conduit (7) into an inlet chamber (7a) below the outer cyclone and in communication with the inner cyclone. On contact with a stator (10), bubbles are generated which form a froth with hydrophobic particles in the feed. The feed passes up through the inner cyclone (2) and the froth is collected at the top of the cell. Exposure of the feed to shear, and hence froth formation, is enhanced either by recycling the feed through the outer cyclone into the inner cyclone, or by increasing shear and circulation within the inner cyclone by the use of flow modification assemblies therein. Residual feed and non-hydrophobic particles are re-covered from the outer cyclone (4) via an outlet (15). <IMAGE>
