    CHEMICAL BENEFICIATION OF LOW GRADE COAL A REVIEW

    Physical beneficiation of coal is not very effective in separation of the finely dispersed minerals, whereas chemical beneficiation uses expensive reagents and leads to generation of large amount of wastewater which needs to be purified before discharge. Thus, a combined approach consisting of physical and chemical cleaning of coal appears to have a potential for. significant reduction of ash
