Hardgrove grindability index (HGI) This measure of grindability of coal was developed by an American, Ralph M. Hardgrove. The test involved indicates how difficult it would be to grind a particular coal to a certain particle size.,Iron ore fines are the principal iron source for steelmakers, but without such agglomeration they would be,

Apr 01, 2018· Other grindability indices are used to describe the performance of a fuel in different pulverizers, for example the impact grindability index or the bond work index. The determination of the Hardgrove index is an empirical test, in which the fuels are pulverized in a mill and the results of a sieve analysis compared to a calibration curve,

The “roasting” of 100 g of a copper ore yielded 75.4 g of 89.5 % pure copper. If the ore is composed of Cu2Sand CuS with 11.0 % inert impurity, calculate the percent of Cu2S in the ore. A. 62 % B. 38 % C. 74 % D. 28 % 11.

The ball-mill grindability index, in percent, is found by dividing number of revolutions into 50,000. In the Hardgrove test, a prepared sample receives a definite amount of grinding energy in a miniature pulverizer; results are measured by weighing amount passing a 200-mesh sieve.
