Critical importance of pH and collector type on the flotation of sphalerite and galena from a low-grade lead–zinc ore

Abstract Collector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type parameters on the galena and sphalerite flotation from a complex lead–zinc–iron ore was investigated. The ethyl xanthate and Aero 3418...
