Currently, there is no standard recognized bench-scale laboratory test for sizing or modelling a high pressure grinding roll (HPGR) in hard rock mining. As a result, metallurgical studies are prohibitively expensive and not economical for early-stage projects. To be adopted as a standard industry test for the HPGR, a bench scale test must: 1) use the same breakage mechanism as …
