I examined the washability characteristics of British Columbia coals in relation to the lithology of the seam, and established a washability parameter that can be related to the inherent coal characteristics. This allow geologists to predict the quality of coal in terms of washability. I published a manuscript-type paper (solo authorship) on .Contact Supplier
Washability Characteristics of Low Volatile Pakistani .
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.Contact Supplier
