Study on Treatment and Reuse of Wastewater from Yunnan Huize Pb-Zn Ore Flotation

Abstract:

In this paper, treatment and reuse of wastewater generated from Pb-Zn sulfide Ore flotation with butyl xanthate and amino dithiophosphate as collectors were studied respectively. The impact of directly reused wastewater on galena flotation was investigated. The results indicate that lower recovery was achieved when the wastewater was directly reused in the process of galena flotation whereas 90% of recovery was achieved as the wastewater was treated by ozone, activated carbon and resins before reusing.
