When a mixture of fine material is ...

PDF COAL BENEFICIATION IN INDIA Observer Research Foundation

Coal beneficiation is a process where coal is subjected to a medium of defined specific gravity. Heavier coal sinks (rejects) and lighter coal floats (clean coal). This specific gravity is defined by the 'washability' characteristics of the coal seam. It is different for different seams in the same area and for different geographical areas.
