Study on the New Technique for High-Sulfur Lead-Zinc Ore of Laos

Abstract:

This study presents sulfide ores with lead 0.71%, Zinc5.07% from Laos, using a grinding (grinding fineness -0.075mm, 80%). Then, the lead ores is recovered by flotation first. Second, the middling ores is returned in preferential floatation. The mixed collector is used in all flotation such as ethyl xanthogenate , butyl xanthate and SN-9.After flotation, the grade of lead concentrate is 63.63%, and a recovery is 83.26% .In addition, the grade of zinc is 56.33%,a recovery is 86.63%. It can result in obvious increase in yields of mineral processing and economic better effect in production, compared to the old technology.
