  • Use more flexible comminution circuits | Energy EXchange

    Since the early 1980s, many mining companies have moved to using a single comminution circuit with very large semiautogenous grinding (SAG) mills.[1. Powell MS and Bye AR (2009) Beyond minetomill: Circuit design for energy efficient resource utilisation] This approach has enabled expansion into processing large, lowgrade ore bodies and to treat large volumes.
