Autogenous plus Ball Mill has been used very infrequently. When hard ores are encountered for extensive periods, 100 mm balls are added to the primary mill (#7). Semiautogenous-single stage. These circuits are not a good choice for many orebodies because it is not logical to expect one machine to be as efficient on 150 mm ore as it is …
