FLOTATION MACHINE Russian patent published in 2012 - IPC B03D1/14 

FIELD: process engineering.

SUBSTANCE: invention relates to flotation and may be used for separation of three-phase pulp in metallurgy and chemical industry, as well as treatment of effluents. Proposed machine comprises, at least, one flotation chamber defined by bottom, lengthwise walls and partitions with pulp overflow openings and furnished with pump aeration assembly, frost concentrate collection and discharge assembly arranged at flotation chamber top, as well as initial pulp feed assembly and flotation tailing discharge assembly arranged at flotation machine outlet end. Lengthwise walls are bent in, at least, one point. Note here that distance from machine lengthwise axis to band point exceeds 1/2 of flotation chamber depth. Note also that inclination of lengthwise walls to bottom varies from 5° to 45°; while flotation chamber has mouth arranged at its top in symmetry about machine lengthwise axis. Note also that mouth base width does not exceed flotation chamber depth while its height does not exceed 1/2 of chamber depth.

EFFECT: higher efficiency, quality and yield.
