Influence of Flotation Reagents on Utilization of Complex and Refractory Lead Oxide Ores

Abstract:

The study aimed to explore appropriate flotation reagents to utilize lead minerals from complex and refractory lead oxide ores in Yunnan. Based on the research on the properties of the material, the reagent regime was investigated and a technological flowsheet consisting of one roughing flotation, two scavenging flotation and two concentrate flotation was adopted to perform the closed circuit flotation experiment. The optimum regulator of flotation experiment was determined as sodium silicate, sulfidizing agent as Na₂S and collector as isoamyl xanthogenate. Under such a condition of reagent types and their appropriate reagent dosages, a lead recovery of 76.55% with a concentrate grade of 58.67% was obtained, which effectively improved utilization of lead resource.
