Abstract

may be used. The gas is supplied at low pressure to the chamber and the resultant depression at the core of the vortex aspirates froth from a container 1. The liquid and gas discharged through the outlet 8 are collected in a radially symmetrical vessel 10 where the separation continues. Liquid and gas are discharged from the vessel through outlets 12, 11 respectively. In a modification (Fig. 3, not shown), the rotation chamber is disposed with its outlet uppermost at the bottom of the receiving vessel which has an axial gas outlet at the top and a tangential liquid outlet at the bottom. Suction applied to the outlets of the vessel causes gas to be drawn into the rotation chamber to form the vortex and the depression at the centre of the vortex draws froth into the chamber. In a further modification (Fig. 4, not shown), the rotation chamber and the receiving vessel form a cylindrical unit having a horizontal axis. Before separation the froth may be separated from liquid by the method described in Specification 734,460. A screw conveyer may be used to facilitate the supply of stiff froth to the core of the vortex. Dimensions are given in the Specification.
