Use laboratory tests to develop the hardness variability function for a new ore body and use this data to design the SAG mill. L. Getting More From Drill Core . Restrict pilot plant SAG mill testing to confirming the design power levels on an ore sample or samples of known hardness.
A research program was therefore initiated at the JKMRC to study this aspect of mill operation. This paper presents the results obtained to date from experiments carried out in a laboratory SAG mill with grateonly as well as grate and pulp lifter arrangements.
