The origins of the RoM mill also drove the philosophy of single stage grinding to final product, nominally 75% to 80% passing 751lm. Much of the early AG/SAG model development work at the JKMRC was based on Australian and North American style mills and operations and hence had not been validated under typical South African RoM mill conditions.
