By the 1910s, the firm's Australian process was generally accepted as so great an advance over any process known before that it promptly came into extensive use for the concentration of ores in most of the principal mining countries of the world. It largely replaced all earlier ore extraction processes and is today known as froth flotation.
The process proved successful at their Central Block plant, Broken Hill that year. Significant in their "agitation froth flotation" process was the use of less than 1% oil and an agitation step that created small bubbles, which provided more surface to capture the metal and float into a froth at the surface. [30]
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. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. [19]
Copper-sulfide-loaded air bubbles on a Jameson Cell at the flotation plant of the Prominent Hill mine in South Australia. The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of ...

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.
It is based on the froth flotation mineral separation process, first invented in 1905. [3] [4] [5] In the coal industry alone, Jameson's cell has retrieved A$ 36 billion worth of export coal particles. [2] It is being used worldwide in the separation of coal, copper, lead, nickel, platinum, silver and zinc. [3]
