Jameson Cell is a top-intensity flotation cell aimed at creating better, faster, and more efficient floating systems. It was created by Graeme Jameson, a renowned laureate professor at the University of Newcastle located in Australia. The ground-breaking cell resulted from a partnership with a then fast-growing mining firm, Mount Isa Mines Limited.

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.

Sulfide Mineral Flotation Maurice C. Fuerstenau, Subhash Chander, and Ronald Woods INTRODUCTION Froth flotation was developed at the Broken Hill mine, Australia, a century ago with the flo- tation of the common sulfide mineral, sphalerite. With this development, billions of tons of worthless rock containing a variety of valuable metals became ore.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Froth flotation is a predominant process for separating, purifying, and enriching industrial metal minerals, nonmetal ores, and coal based on the difference in surface wettability, .In froth flotation, a collector (a special surfactant) selectively clings to the desired mineral particles in slurry to make their surface hydrophobic; then, the hydrophobic particles are separated from other ...
