1. Introduction. A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 JKMRC CO. 2006.This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill
