Copper - C70310 Alloy

To be noted that the reduction ratio calculated at the mill is almost constant above 400 TPH regardless of the ball size (Millpebs, 12 mm and 25 mm), the ore type (Cu-Mo vs Zn-Pb ore) and the feed size (below 140 μm versus above 350 μm). This can be easily explained by an extremely low residence time.
