8.6.1 Froth Flotation. There are various methods available for cleaning fine coal, of which froth flotation has become the most common practice. 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%.
Consequently, aside from a few fundamental principles regarding flotation and the use of reagents, it is generally agreed each ore must be considered a problem for the metallurgist to solve before any attempt is made to go ahead with the selection and design of a flotation plant. Types of Flotation Reagents
While many types of agitators and aerators will make a flotation froth and cause some separation, it is necessary to have flotation cells with the correct fundamental principles to attain high recoveries and produce a high grade concentrate.

The basic coal flotation technology has been derived from ore flotation, where the technology has been extensively used. The first froth flotation plant for coal was established in the United Kingdom in 1920 and the first US plant was established in 1930. Froth flotation technology has made substantial progress over the last fifty years.
