Among the different grinding processes, Autogenous (AG) and Semi-Autogenous (SAG) mills are widely used for ore size reduction. The main difference between these two mills is the use of steel balls as grinding media, typically in the order of 6–12% in volume (Sbarbaro et al., 2005), in the SAG mills. With the addition of grinding …
