Sustainability of coal mines: Separation of clean coal

网页2021年5月1日However, it is reported that the Falcon concentrator is not efficient to beneficiate coal below 45 μ. Hence, in this article, an attempt is being made to separate the clean coal by the concept of wet grinding followed by the density-gradient-centrifugation technique. This has the advantage of high clean coal yield with minimum water content.
