For forward fed circuits (e.g. primary ball milling), a size distribution of the combined mill feed (circuit new feed and c yclone underflow) is required. While not as straightforward as taking the CUF as total ball mill feed, forward circuit mill feed can be obtained via a good survey and mass balance. Once the laboratory has completed the size distribution analysis of the ball mill feed

The computation of a Bond ball mill work index was empirically calibrated by Fred Bond using a short ton basis. The modern (metric tonne) basis is the following equation: NI43-101 reports often provide P 100 and the work index. To estimate the other parameters, you can assume: the P 80 is 0.92 (P 100, m) 0.96 (see below for details)
