Column Flotation Eriez Flotation DivisionFlotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell.Column Flotation Cells Mineral Processing amp; MetallurgyColumn flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles.COLUMN FLOTATION MODELLING AND sequentia
