feed size distribution is different to a standard Bond ball mill work index test. A series of 10 samples for an Andean copper project were treated to both the SAGDesign (and Sd_bwi) test and the standard Bond ball mill work index test with 180 µm closing screens. The SAGDesign results (with the non-standard ball mill feed) are given in Table 1.
