Coal Beneficiation Technology 2007 Initiatives, Policies

2013-2-21  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.

Coal beneficiation technology to reduce hazardous

Coal beneficiation is a process to remove mineral matters and sulfide minerals from the coal to meet the market criteria such as ash, moisture, sulfur, and heat content (Noble and Luttrell, 2015, Miller, 2017), and coal with a higher heating value is obtained after the beneficiation as the ash and sulfide-bearing minerals are removed from the coal.

Coal Beneficiation Technology for Coking & Non-Coking

2016-5-14  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%. Now-a-days, Ministry of Environment & Forests has put restriction on the use of high ash coal in power sectors, which necessitated priority to wash non-coking coal also. The choice of process equipment involved in coal washing depends on factors such as the type of coal
