uniform final product size flotation cell for minerals

  • Minerals Free Full-Text Enhancing Ion Flotation

    Conventional ion flotation is hydrodynamically constrained by coupling of the gas flux and liquid flux that report to the concentrate. This constraint has greatly limited the industrial application of ion flotation despite its remarkable effectiveness in extracting ionic species down to very low concentrations of order 1 ppm. Previous work demonstrated that these hydrodynamic constraints

     · applying coarse flotation a smaller percentage of the ore will be finely ground and lost during flotation." Another significant benefit of coarse flotation is that it results in a much coarser final tailings product. "The industry currently produces fine tails which are more chemically reactive and difficult to dewater " explains Wasmund.
