2021-5-19  The signature plot for the Ernest Henry magnetite circuit in Australia is E_fine = 3×10 6 × (40) -3.1385 (Burford, MetPlant 2008). The Ernest Henry tests were performed at about 100 µm feed to the vertical mill. So using that equation, your specific energy requires E_fine = 3×10 6 × (40)
