Energy and Cost Comparisons of HPGRbased Circuits | E MJ
The Huckleberry mine, located in British Columbia, produces roughly 40 million lb/y of copper. A comprehensive energy and cost study compared an existing SAG millbased circuit at the Huckleberry mine with two proposed circuits involving comminution technologies that are associated with energy efficiency: highpressure grinding rolls (HPGR) and highspeed stirred mills.
