Nov 09, 2017 Coal Washing Plant. The calculation of the performance of coal washing units that are in common use is not difficult and the principles of making such calculations have been known for many years. The flowsheets to be simulated consist primarily of coal washing units each with a target specific gravity of separation specified for each washing unit.
The process of coal cleaning must be tailored to the specific characteristics of the raw coal at hand and the quality of the clean coal that can be achieved using specific equipment. Coals from different beds have different properties. Coal from the same bed, mined at different locations, may not display the same response to coal cleaning.

The FGX dry coal washing process is proven successful, cost effective, environmentally friendly, and requires only an air quality permit. Coal mining typically results in the recovery of rock that ranges from small to very large quantities depending on geological characteristics of the seam being mined.
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.
