As the reserves of good-quality coking coals of upper seams are almost depleted, low volatile medium coking (LVMC) coals of lower seams have become the alternative choice. These coals, being of lower seams are likely to be more mature (R o ~1.3) than the upper seams and consequently exhibit lower values of volatile matter (Kumar and Saxena, 2014).

Through washability study, a couple of parameters were investigated for a low volatile Pakistani Coal (coking). The aim was to find out the effect of the action of reducing material release characteristics for low volatile Pakistani coal. The "Index of washability" (IW) and "Near gravity material Index" (NGMI) were used as parameters to express the ease of washability.

Indian coals of Gondwana origin are heterogeneous in nature and constitute about seven percent of the world's proven coal reserves. As on today, the total reserves of coal in india is 277 billion tones. Out of which about 83% constitute non-coking coal, 14% coking coal and the rest are others. Coking coal is an essential input for production of Iron & Steel through blast furnace route.

Conventional method like washing for coal is inescapable. Indian coals are generally difficult to wash because of the intimate dispersal of mineral matter in the coal substance which results in an appreciable loss of combustibles during washing in the form of middlings and rejects (1). Coking properties of coals are extremely ash sensitive.
