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.
