摘要

A rougher flotation tailings sample from a Cu–Mo operation was treated in this work to investigatepossibility of re–treating the tailings sample for possible recovery of both molybdenum and coppercontained in the tailings to offer as additional resource. The as received samples were first preparedby drying and milling to pass 100 μm screen to be used for all experiments. Characterisation by XRDshowed pyrite (FeS_2) and quartz (SiO_2) as dominant phases and chemical analysis showed copper andmolybdenum contents in the tailings as 0.56 per cent Cu, 0.37 per cent Mo and around 40 per cent Feindicating that the tailings sample contains over 90 per cent FeS2. Several experimental conditionsincluding; slurry pH, flotation time, collector and frother concentrations, pyrite depressant wereinvestigated in a 0.5 L (500 ml) laboratory flotation cell to obtain best conditions for recovery of bothcopper and molybdenum.The experimental results obtained show that at pH 11 grades of both Mo and Cu can be improved.In a first-stage flotation using a mixture of reagents (1 per cent sodium dodecyl sulfate (SDS) (30 ml)+ kerosene (3 ml) mixed in 100 ml water) Mo and Cu recovery of 60 and 20 per cent respectivelygiving Mo and Cu grades of 7.40 and 2.71 per cent respectively with the addition of tannic acid aspyrite depressant. Cleaning of concentrate in the first-stage flotation, employing re-grind of samplesto –75 μm, and addition of PAX assisted to improve both Mo and Cu grades in the final concentrateand results are discussed in this paper.
