  • Vertical Froth PumpsSALA Type

    Froth pumps are vertical shaft slurry pumps with integral sumps generally used on the output from froth flotation cells. Centrifugal pumps cannot pump froths, and therefore require sufficient volume in the sump to hold the froth until broken down to a liquid. The froth is broken down by being sheared in the sump either by reverse swirl spirals at the entrance to the pump, or by mechanical agitators on the pump

  • What is Froth Flotation?

    May 22, 2020· Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

  • Froth Treatment ExplainedOil Sands Magazine

    Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbonbased gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphthabased hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.
