COLUMN FLOTATION MODELLING AND TECHNOLOGY

Industrial flotation columns are square or circular, typically 0.53m in diameter or side, and 1215m height. Since their invention, square columns have been marketed commercially by the Column Flotation Company of Canada Ltd. The apparent simplicity of the column has led others to copy the original idea and make their own quot;homemadequot; columns.

Imhoflot Pneumatic Flotation PlantsMaelgwyn Mineral

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications. This has led to the development of the patented Imhoflot GCell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment countercurrent to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed
