beneficiation of coal process:

Coal Beneficiation - an overview ScienceDirect Topics

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Coal Beneficiation Technology - 2007 Initiatives, Policies ...

Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.
