• Power efficiency is demonstrated by Figure 3, comparing the power required to grind a gold ore in a ball mill with 9 mm balls with an IsaMill with 2 mm media. The IsaMill is much more efficient below about 30 µm – to grind this ore to 15 µm would take 28 kWh/t in the IsaMill, but 90 kWh/t in a ball mill. Traditionally this has been
