Abstract: A copper-molybdenum tailing with size distribution of -0.074 mm 68.63% is fine.Rutile is content of 0.31%,and obviously enriched in 0.037 ~ 0.010 mm size fractions,with single liberation degree of 72.80%.Gangue minerals are mainly quartz,and amount of easily sliming chlorite and clay minerals.In order to improve the comprehensive utilization of resources,realize rutile recovery from the tailings at low cost and high efficient,beneficiation experiments on rutile are carried out with no grinding operation,through two roughing-four cleaning-one scavenging,mixing concentrate of scavenging with tailing of first stage cleaning,other middles return to the flow-sheet in turn.Finally,rutile concentrate with TiO2 grade of 64.59% and recovery of 77.25% is received,realizing better rutile recovery index.
