| Abstract Scope |
Jamesonite is a natural source of lead with the formula Pb4FeSb6Pb4, commonly associated with undesirable sulfide minerals such as pyrite. During flotation separation, this phase floats freely with valuable minerals. Alternative non-toxic reagents such as thioglycolate (TG) have been proposed to suppress pyrite, showing good effectiveness. However, the effect of TG on collectorless flotation of jamesonite is unknown. This research investigates flotation in the presence of thioglycolate. The results indicate the depression of jamesonite at pH 6.0, 8.0 and 10.0 the maximum depression is with 0.25 g/L of TG obtaining a flotation of 27.2% and 19.09% w/w for pH 6 and 10. On the other hand the surface of the lead mineral is activated during the flotation without collector at alkaline pH of 12.0 and for all the proportions of TG used (0.25, 0.5, 1.0 and 1.5 g/L) obtaining around 97% w/w of cumulative separation after ten minutes of processing |
