Column flotation cells

When it comes to froth flotation and recovery, there is no one-size-fits-all solution; instead, mining sites find that the best route is to combine multiple pieces of froth recovery equipment, to create a hybrid circuit solution capable of ensuring the best possible recovery rates. Column Flotation Cells are an integral part of that circuit.
