Coal beneficiation: Policy priorities for India | ORF
1. RATIONALE FOR COAL BENEFICIATION. 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 kcal/kg).
