Coal Beneficiation Technology for Coking & Non-Coking Coal ...
Clean coal technology being practiced in coal washeries in India, as pre-combustion clean coal technology, mainly focus on cleaning of coal by removing ash from coal. Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18%. The raw coal ash in Indian coking coal varies from 25 to 30%.
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.
