Fly Ash Separation with a Nash System Gardner Denver Nash The RockTron PFA (Pulverized Fuel Ash) Beneficiation Process uses an improved "froth flotation" technique which uses water. This newly developed process has the advantage of not creating excess dust and avoids many other environmental issues.
In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation…

Therefore, the coupling of multiple flow fields and force fields will make the flotation become the most promising method for separation unburned carbon from fine coal fly ash in the future. Other separation methods may be useful for specific material properties, such as incipient fluidization, acid digestion, and thermal processing [ 7, 27 ].
