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.
Froth flotation technology has made substantial progress over the last fifty years. Coal is a solid combustible material and exists in the ground along with impurities. Coal, being composed of carbon elements, is hydrophobic in nature and thus is a good candidate for the froth flotation technique.
Provision to remove froth by the use of froth paddles on all flotation cells should be included in the original design. The additional capital cost required for froth paddles is a reasonable investment since these devices tend to negate errors in flotation pulp level or frother addition.

of impeller speed. The mechanism design is critical to ensure effective air-pulp mixing and dispersion within the cell. The low pressure DR flotation machine requires air. An air pipe surrounding the impeller shaft leads directly to the centre of the impeller. DR flotation machines 2 DR Flotation
Column flotation devices were re-introduced for mineral processing in the late-1960's in Canada by Boutin and Wheeler (1967) at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product.
The graphic on the left is a "middlings thickener". The bubbles that flow over the edge of the first set of flotation tanks (inside the mill building) end up in this thickener. By then the bubbles have broken and the slurry is poured into the center of this round tank.

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.
And as a comment, I have witnessed more voodoo and spurious claims of efficiency in the froth flotation machine design than anything since the snake oil days of the Old West. It is generally wise to stick with a good brand that is widely utilized in flotation of the mineral desired.
