Coal cleaning by froth flotation

Appalachian coal, it produced a cleaner coal product than conventional macro-bubble flotation. A general kinetic model was proposed to represent the rate of flo­ tation of coal. For two Appalachian coals, the model successfully represented the flotation kinetics of uniformly sized coal. The pro­ posed model also represented well the flotation kinetics of coal consisting of two sizes of ...

Float-Sink (Washability) Test, Coal Analysis, Kentucky ...

2020-07-27  The single float-sink test defines the relative amount of float-product and sink-reject that should result from the coal being washed in that preparation plant. The second type of float-sink analysis tests a coal sample in a succession of density baths to determine the optimal density for separation of the coal from rocks and minerals.

Coal Washing Encyclopedia

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.
