Grinding media and wear lining costs range between 0.41 $/t and 1.82 $/t. Option 3 has much higher media and wear lining costs because two ball mills of 8.8 MW installed power each are required to grind 8 Mtpa of RMS concentrate from P80 2.3 mm to P80 75 μm. The overall OPEX for Option 3 is the highest due to the high costs of media and liner ...

x) For increasing the stability of magnetite suspension, a stabilizer is re-quired to he added in the suspension. xi) Ball mill grinding incurs high power cost hence, the operator should be skilled and trained for optimal use of the machine. xii) A proper maintenance management is essential for smooth operation. CONCLUSIONS

This paper studies the grinding behaviour of vanadium-titanium magnetite concentrate in a ball mill. The grinding kinetics, surface morphology, lattice distortion, wettability and moisture capacity were analysed. Grinding kinetics equation was established based on population balances model with the size distribution data from a laser diffraction technique.
