• Grindability as indicated by the bond ball mill work index (BWi) ranged from 10–35 kWh/t, with the majority between 15 and 27 kWh/t. No clear relationships in terms A*b and/or BWi was identified with geological aspects logged from the drill core such as weathering, lithology, alteration, alteration intensity, veining or combinations of these.Determining the Bond Efficiency of industrial grinding circuits,Where, WioACTis the Actual Operating Bond Work Index (kWh/t), W is the specific energy input (kWh/t), P80 is the 80% passing size of product (µm), and F80 is the 80% passing size of circuit feed (µm). 2. Calculate the Standard Circuit Bond Work Index (WiSTD) for the material being processed (equation 3). Wtotal
The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of –0.45 in the 100 µm to 200 µm size range, not the –0.50 exponent empirically measured by F. Bond. The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energyTable of Bond Work Index by Minerals Mineral Processing,619· Table of Bond Work Index by Minerals Table of Bond Work Index by Minerals This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ‘around the world sample’.
