  • Column and Contact Cell Flotation Mining SGS

    As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs.

    The authors have studied the recovery of fine resin particles by froth flotation, using the model copper Dow XFS4195 chelating resin system. As the functional group on the resin is a bis picolylamine, the resin should be amenable to flotation by anionic collectors, such as sodium dodecylsulfate and sodium dodecylsulfonate.

  • Flotation cells Selecting the correct concentrate launder

    As with the internal peripheral launder the froth is pushed to the launder by the froth crowder. This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells.
