beneficiation of difficult to wash low volatile coals
Definition of coal Auroma
products: a lowash coking coal cleaned to acceptable coking properties, including low sulphur; and a mediumash stemcoal obtained by cleaning to a higher separating density. Three products separations, low ash, medium ash and discards, are becoming increasingly common where coking coals are to be obtained from dirtier run mine coals.

Anthracite Coal |
Sep 08, 2018· When burned, it produces a very hot pale blue flame. It produces more heat than many other coals. The coal is slowburning and difficult to ignite because of its high density. The low sulphur and volatile content in anthracite coal makes it an extremely clean burning fuel. Anthracite coal produces virtually no smoke or particulate emissions.
