copper ore dolomite bond grinding

Determination of the Bond work index on samples of non ...

21/11/2012  For the samples used in the present investigation, the following results were obtained for k F: 0.74 for dolomite, 0.70 for copper ore and 0.80 for quartzite. When the Bond test is realized on a sample of non-standard size, then the value for k F is unknown. Then, values for k F closer to 0.8 are chosen if the materials are harder.
