Reclaiming the Mine; No gold (PDF) Gold Extraction and Recovery Processes For ,Grinding and Sizing Ore is stockpiled at the mill before being fed into a semiautogenous grinding (SAG) mill with lime, water and steel balls. The larger particles from this mill are returned to the SAG mill for more grinding. The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% <70 microns.
