Organorefining is a process of solvent extraction through which organic matters are extracted from coal using organic solvents. Indian coals have high mineral matter content ranging from 25 to 45 wt.% (dry basis). The ash in coal is highly disseminated, which makes it difficult to remove by physical beneficiation.
