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.
