The attraction of semiautogenous grinding in copper operations is that they can accommodate ores that are hard or soft wet or dry sticky or otherwise The SAG mill can handle everything that is presented to it regardless of coarseness or fineness or hardness or moisture content and from it prepare satisfactory feed for subsequent secondary grinding by conventional means to the required flotation product sizing...
