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 to separate plastics, Argonne National Laboratory Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste ...
The company holds many patents for cable-operated digging equipment, such as Dragline excavators and power shovels, such as the Insley model k12. Insley lost its independence in 1975 when purchased by United Dominion Industries ; the name is currently held by Badger Equipment Co. [ citation needed ]

Bitumen froth treatment is a process used in the Athabasca oil sands (AOS) bitumen recovery operations to remove fine inorganics—water and mineral particles—from bitumen froth, by diluting the bitumen with a light hydrocarbon solvent—either naphthenic or paraffinic—to reduce the viscosity of the froth and to remove contaminants that were not removed in previous water-based gravity ...

In 1907, William Emmett Urschel began experimental work on a gooseberry stemmer. [1] Urschel received his first patent for the Gooseberry Snipper in 1908. In 1910, Urschel founded the Urschel Gooseberry Snipper Factory, a small two-story wooden shop at 158 South Napoleon in Valparaiso, Indiana, located next to his residence and in an area populated with gooseberry farmers.
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. The released air forms ...
