A variable in the flotation circuit design is to include column cells in the cleaner circuit in order to improve the gold concentrate quality and to reject insoluble material. Column cells are particularly important when the ore present high content of silicates, carbonates and clays, which affect thickening, filtration and concentrate grade.
Imhoflot TM flotation was introduced to the mining industry more than 25 years ago by Maelgwyn. Over the years the flotation cell design has been optimised for different applications; including vertically fed (V-Cell), tangentially fed (G-Cell), hybrid (H-Cell) and VC-Cell as the latest design for coarser particles.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …

Further, the inclusion of unit and flash flotation cells will generally provide better flotation stability and performance. Improved overall gold flotation recoveries from 3% to 10% have been quoted (Sandstrom and Jonsson, 1988, Jennings and Traczyk, 1988, McCulloch, 1990) for ores of variable gold and sulfide content (Taggart, 1945).
In the present work, the solution to the problem of low gold and silver recovery was obtained by making interesting changes in the grinding circuit which included a flash flotation …
