Read MoreDue to their relatively low energy requirements, both these mill types are also being increasingly used for secondary and tertiary grinding as replacements for ball mills [8, 9, 10]. The decreasing mineral grades in the ores have also led to increased throughput rates in the flotation stage (Fig. 15).
