Abstract USGS

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 Cyclone undersize is sent to the first product rougher flotation cells These rougher con
