EXERCISE 6-5 Ball milling circuit using time-based model - Porphyry

Repeat exercise 6-1 using the Austin model for the rate of breakage and the default values for porphyry ore. The specific gravity is 2.7 and the bond work index is 28.5 kWhr/tonne. Because this ore is so tough a larger ball mill will be required so increase the residence time to 15 minutes. A much larger circulating load will be required so increase the cyclone diameter to 76 cm and put 20 cyclones in the cluster.

Run the simulation and record the results as before.
