The 80% passing size P of the broken rock must be measured by size analysis or must be estimated to obtain the blasting work index. Two blasting tests (Bond, 1954) on Taconite iron ore in Minnesota five years ago gave work index values of 14.5 and 13.5, or an average of 14.0, which compares with 14.7 recently obtained in crushing this ore in
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes
