Knowing the Hardgrove indices, the Bond work indices of some samples were estimated using the Aplan's formula. The approximate work indices were determined by running a batch drygrinding test using a laboratory ball mill. Finally, the work indices obtained from both methods were compared. It was found that all samples could be ranked as lignite B, using the heating value as criteria, if the ...
