Gamal, 2012). The Bond work index is regarded as size reduction resistance. It can therefore be presumed that the BWI is correlated to the physical and mechanical properties of materials (Mwanga et al., 2015). The number of grinding stages and necessity of intermediate grinding can also be predicted together with evaluating BWI
