Pneumatic flotation - a modern alternative

International SAIMM Colloquium: Developments in Froth Flotation: Volume 2, Cape Town, South Africa, 3-4 August 1989. - 26 p.Pneumatic flotation, a development of the past 10-15 years, is fundamentally different to pneumatic systems already known, particularly to column flotation. The basic principle, process kinetics, technique of the apparatus and economic advantages are presented. Results from two operating units for coal are supplemented by results of pilot tests with petrol coke, graphite, fly ash and oil-contaminated effluents.
