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).
