What Can Go Wrong in Comminution Circuit Design?

• SAG Mill Design Test (Starkey, 2006). There are reasonable correlations between all the tests' data that generally allow any or all of the data to be used to design a SAG mill based grinding circuit for 'typical' ores of a moderate competence range. Issues have arisen where the expected SAG mill specific energy is greater than 10 kWh/t.
