The Bond Ball Mill Test Work Index of the ore was measured to be 15.8 kWh/t. Then, takg Work Index Efficiency as the ratio of Test WI / Operatg WI, it equals 15.8 / 14.4 = 1.10, or 110%. This circuit is approximately 10% more efficient than the average circuit upon which the Bond design method is based.
