Application of IMHOFLOT G-cell centrifugal flotation technology

The Journal of The Southern African Institute of Mining and Metallurgy, #17, October 2007. - pp. 623-631 (non referred author's e-copy)The Inhoflot G-cell, a new development in the pneumatic flotation technology (which incorporates centrifugal forces in the separating vessels), is a recent innovation in the mineral processing world. The G-cell was invented by Dr. Rainer Imhof and commercialized by Maelgwyn Mineral Services Ltd. In a short time span a number of plants and units have been successfully commissioned in the mineral processing industry. In addition, a number of industrial G-cell flotation plants are in the process of construction for the purpose of coal preparation and environmental remediation. In this paper two industrial installations have been highlighted, together with a pilot plant test programme investigating ultra-fine flotation recovery for a base metal operation.
