Flotation Froth an overview ScienceDirect Topics

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.

Copper extraction Wikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

Paraffinic Froth Treatment Oil Sands Magazine

Froth Treatment is a process by which water and fine solids are removed from bitumen froth produced in Extraction using hydrocarbon-based gravity separation. In a Paraffinic Froth Treatment facility, a paraffinic solvent is used as the diluent, producing a very clean final product that can be sold directly to market without an upgrading step.
