How to use comminution processes for reducing the ore

For example, suppose we have an iron ore of 0.5 meters, and the liberation size is about 400 microns. We need to reduce its capacity to 80% less than 440 microns, at least. If we try to conduct the comminution in one single stage using a mill, we will have several problems. First, the capacity will be deficient. We can not process a large volume of the ore to reduce its size from 0.5 meters to
