· The rock from the crushing plant needs to be reduced typically from the range 1–10 mm down to 0.05–0.1 mm in order for the flotation to work efficiently. For this size reduction, from 1 to 10 mm, down to the range 0.05–0.1 mm, wet tumbling mills are often used, in combination with hydrocyclones for size classification.
