  • Column Flotation Cells - Mineral Processing Metallurgy

    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.

  • Column Flotation Parameters

    As the column flotation cell was shortened, recoveries decreased consistently (Fig. 5). This reduction in recovery substantiates the theory that column length is based on particle retention time. For our purposes, retention time was calculated as plug flow retention time based on collection zone volume and tailings flow rate.
