    1/1/2016· It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semi-autogenous operation with about 8% ball charge was the preferred option. Based on these test results, a 6.7 m diameter × 2.1 m length SAG mill and a 3.3 m × 6.1 m ball mill were installed for commercial operation in closed circuit with a hydrocyclone.
