The intrinsic quality of Indian coal, along with the dominant practice of open cast mining, has meant that run of the mine ROM Indian non-coking coal contains a huge share of ash and other minerals. ROM coal typically has high ash content from 30-50 percent and low calorific value 2,500-5,000 kcalkg.Nov 03, 2015 Coal is treated in processes called beneficiation to prepare a material that meets the certain requirements. These processes may result in low ash quantity . GK, General Studies, Optional notes for UPSC, IAS, Banking, Civil Services.
