    The conditioned mineral slurry is then processed in flotation cells, which are essentially agitated tanks into which finely-dispersed air bubbles are introduced. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral-laden froth.

    The setup in which the froth floatation process is carried out is called the froth floatation column. A common industrial column cell consists of a long cylindrical tank fitted with a feed inlet pipe in the upper portion of the cylinder. Two launders are also connected, one internally and one externally to collect and separate the foam.

  • Froth flotation - Wikipedia

    Froth flotation is a process for selectively separating 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 physico-chemical technique used to separate the constituents of a mixed mineral slurry by their relative surface hydrophobicity. In order to do so economically, it is necessary to treat large volumes of material in ever-larger and more efficient tanks. The efficiency and efficacy of such tanks can be enhanced through mechanical modifications designed to improve froth ...
