2.1 Froth Flotation Froth flotation, which was commercially introduced in mineral industry early in the 20th century about 100 years ago, is applied in many instances in the primary mineral industries for separations of solids. Besides mineral industries, flotation can also be used in wineries, food factories, smelters and refineries.

Celanese - The chemistry inside innovation

In these cases, the initial ore could contain between 0.1-0.5% of the desired metal or mineral and following the flotation process the grade can increase to 20-25%. However, the froth flotation process is also used to extract coal, iron, potassium chloride, phosphates, and – in the paper recycling industry – for deinking paper fibers.

Flotation Machine - an overview | ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.

Froth Flotation Process - Mineral Processing & Metallurgy

FROTH FLOTATION “So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined.” The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

AMIT 145: Lesson 5 Froth Flotation – Mining Mill Operator ...

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

Coal Washing | Encyclopedia.com

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
