The geological grade of the ore deposit is relatively high (about 50 ), but the ore body is thinner or has interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.Apr 04, 2014 Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient.There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.
