Description:Total grinding power consumption decreases and SAG mill capacity increases significantly. Later tests, with other types of ore, have shown lesser differences between those size distributions. However, the effects on power consumption and mill capacity have been the same, confirming the strong effect of small variations in the ultrafines production.
