Fig. 2, Fig. 3 plotted ln(m 1 (t)/m 1 (0)) as a function of grinding time t for quartz and chlorite at various feed size fractions during wet ball grinding, respectively. As can be seen, ln( m 1 ( t )/ m 1 (0)) showed a good linear correlation with grinding time t in the range of feed sizes investigated.
