Comminution Circuits for Gold Ore Processing ScienceDirect

Jan 01, 2016· Such a circuit can counteract the effects of harder ore, coarser ore, decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the
