The HPGRball mill circuit was estimated to require 75% of the energy of a standard semiautogenous grinding (SAG) mill circuit. Even with an anticipated greater capital cost, the HPGRball mill circuit was found to give significantly better financial returns in all cases investigated in the feasibility study.

High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. The use of a small lockedcycle scale test, such as the Bond ball mill grindability test, was proposed as an alternative way to achieve the same objective in a more controlled manner, and more importantly, with a smaller .
