    1 Introduction Finding the bond work index of an ore type is crucial to determining the grinding energy required during comminution in a ball mill. The bond work index is a constant characteristic related to the hardness of a specific ore type. Bond work index is one of three different approaches that can be used to calculate the work index of an ore.
