Oilsand froth is difficult to pump at very low speeds and at low temperatures. However above a certain speed in a steel pipe, water may separate and form a lubrication layer. The process is called self-lubrication and depending on the temperature (25 C - 45 C), the friction losses are between 10 and 20 times the equivalent friction losses of water.
Froth flotation cells used to concentrate copper and nickel sulfide minerals. Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles.

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
