Typical values of Bond ball mill work index for soft oxidised ore bodies lie in the range 5-10 kWh t at a standard product size of 80 passing 75 m.
Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index. This is empirical index determined by closed circuit grindability tests developed by F.C.Bond in the mid 1930’s. It requires a specific 305mm diameter x 305mm long (inside dimensions) horizontal axis ball mill without lifters operating at 70 rpm to perform.
