Example 7.2. A mineral of S.G. 2.4 was crushed and the average product size of the largest fraction was 6.25 mm. It was fed to a wet overflow ball mill of I.D. 1.5 m and ground in closed circuit at 75% of the critical speed. The work index of the mineral was 12.8 kWh/t. Estimate the largest size of make-up ball that should be used. Solution

With respect to the crystal structure, typically the transition metal di-borides (in general terms; 2, where M = Zr, Ti, Hf and Ta), tend to possess primitive hexagonal crystal structure of the AlB 2 type (Fig. 3a), with P6/mmm as the space group. It is a layered structure arranged in a hexagonal close-packed (HCP) array with alternating transition metal (M) and …
