Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.

The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3.

Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.
