Dry coal preparation without the use of water • STEINERT
With this method, the de-centralised pre-concentration of coal in small, remote mines allows the coal to be separated from the waste rock, to immense economic advantage. Transport costs are massively reduced, or the coal is sold directly as a high quality product. The use of drum screens is very common in coal beneficiation.

The dry beneficiation of duff coal in a dense medium
Traditionally wet beneficiation is the predominant method in order to beneficiate coal due to its sharp separation efficiency; however large quantities of water are required in order to process the coal. Water scarcity, especially in arid coal rich countries, is therefore encouraging the development of dry coal beneficiation technologies.
