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 ...
And in 1923, Minerals Separation staff chemists in the San Francisco office, Cornelius Keller and Carl Lewis under director Edward H. Nutter, perfected the use of chemical xanthates, replacing the use of oil and easing the workings in the froth cells. The firm moved into research for the use of flotation in nonmetals as well, such as potash.
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 ...
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]

The most common zinc concentrate processed is zinc sulfide, [1] which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide. [2] Approximately 30% of all zinc produced is from recycled sources. [3]
Carrie Jane Everson (born Rebecca Jane Billings; 27 August 1842–3 November 1914) was an American who invented and patented processes for extracting valuable minerals from ore using froth floatation. [1] The Mining Journal noted in 1916 that "as a metallurgist she was a quarter of a century in advance of her profession." [2]
Diagram of a froth flotation cell. Froth flotation was adapted from the flotation process used in the mining industry in the 1960s. It is the most common deinking process in Europe used to recover recycled paper. Often most of the collector is added to the inlet of the flotation. The process temperatures are normally in the range 45 - 55 °C.
