These tests are used here to develop empirical equations from which the work index at different product sizes can be computed from a grindability test at one size. In each of the 15 ores the data from the grindability test at 48 mesh alone were used to calculate the Wi values at 28, 35, 65, and 100 mesh, and these were compared with the actual values obtained by testing. In the calculation the

An alternative approach to determine the effect of closing screen size on the Bond ball mill work index (BW i), in the absence of extensive test work, is to use computer simulation. The batch grinding process has been modelled using the size–mass balance approach (Austin [37] , Chapter 11 ) and if we can do this, then we can effectively simulate the Bond ball mill work index test.
