Abstract

dability of limestone in their mixtures. This behavior may be attributed to the Representative samples of limestone, ilmenite, and quartz, were dry batch ground separately and in binary mixtures of limestone – ilmenite and limestone-quartz in different compositions in the ball mill. The study aimed to investigate the effect of the mixture composition on the mill product characteristics as reflected on each of the two components. The results indicated that quartz affects as a hard component more than the ilmenite as a heavy component on the grinability of quartz to transfer the kinetic energy of the grinding media to limestone component more than ilmenite, which increases the preferential comminution of limestone by quartz more than that by ilmenite.
