  • Flotation Cells For Profitable Minerals Concentration

    Schreiber says that process control in a flotation plant normally can be onerous with controlling slurry level and froth proving inherently difficult in a row of flotation cells “The slurry level in any cell affects the driving head in adjacent cells and this can easily create unstable control conditions.Flotation cells are connected in a network and the tailings stream from one cell is likely to be fed to another cell Similarly the concentrate flows will generally be fed into banks higher up in the circuit This results in strong interactions between levels in a flotation circuit Thus if a change in control action is made at any point in.
