FGX DRY COAL PROCESSING

Such recent advances in the cleaning of finer sizes of coal required that entire coal-magnetite streams, which are normally run over drain and rinse screens for separation of a large portion of the magnetite, be fed directly to magnetic separators.

what is the separation method used in separating coal

A dense medium separation conducted at 1.7 g/cm 3, which would be the most effective separation density for the tested coal at hand, will provide about a 65–70% clean-coal yield (float clean coal) with about a 25–30% ash content for the three size fractions. The reject (sink coal) product would have about 65–70% ash content.
