    Mine-run ore is initially crushed and sized in a series of crushers and vibrating screens to approximately minus 5/8 in. Crushed ore is then ground in rod mills and pass­ed through cyclones. The oversize is ground in ball mills then pumped back to the cyclones to achieve a minus 200 mesh flotation feed.
