A few years ago, FreeportMcMoRan Inc. (FCX) chose highpressure grinding rolls (HPGR) over a semiautogenous grinding mill for the expansion of its Morenci openpit copper mine in Arizona. In February of this year, Iamgold announced it too would be using HPGRs at its new Côté Lake project in northern Ontario. The same month, Altura Mining also revealed it would be using HPGRs for its ...
