Flotation Column Cell

Column 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 Columns are mostly used to produce final grade concentrates because they are capable of high selectivity
