Estimation methodology for Bond ball mill work index …
To determine the ball mill work index of the samples (Table 1), around 10 to 17 kg of ore was required for the particle size crushed to −3.35 mm (Amtech, 2006). The 700 cm 3 ore sample weight is fed to the Bond mill at a −3.35 mm size range. The test was started with an arbitrarily chosen number for mill revolutions (N = 50, 100, 150…).
