Circulating load (theoretical) is usually based on the grinding efficiency of the mills and the separating efficiency of the cyclones, while achieving the desired cyclone o'flow size range. For this you need to simulate the grinding and the cyclone separation. There are software packages for doing this (see Metsim and others) but they are pricey.
