Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

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

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
Any time that you have an overloaded froth condition the OVERFLOW that is going over the side of the cell will slow down as the froth column begins to collapse under the weight of the mineral. The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow.
