Berry and Bruce (1966) developed a comparative method of determining the hardness of an ore. The method requires the use of a reference ore of known work index. The reference ore is ground for a certain time (T) in a laboratory tumbling mill and an identical weight of the test ore is then ground for the same time.Since the power input to the mill is …

The object is to bring the ore to the mesh-of-grind called for by the concentrating section of the mill, and this is best done in separately controlled stages. Often the primary grinding mills must work vigorously on a quickly passing stream of ore, and the secondaries more gently and with longer retention of the pulp.
