Research on Comprehensive Recovery of Copper,Gold,Silver and Iron from Tailings in Tonglushan Mine

摘要：

This paper presents the research on comprehensive recovery of copper,gold,silver and iron from tailings from high-intensity magnetic separation in Tonglushan Mine.By comparison of experimental results of three flowsheets-regrinding of tailings-conventional sulphidizing flotation,water heating enhanced sulphidizing flotation and acid leaching-sulphidizing precipitation flotation,it is concluded that regrinding of tailings-conventional sulphidizing flotation flowsheet has the best economical and technical performance and practicability.Regrinding and using the mixture of sodium hydroxamate and sodium xanthate are two of the notable technical characteristics of this best flowsheet.The system for comprehensive recovery of tailings has been put into production.It not only can recover the valuable minerals from tailings in Tonglushan Mine,but also can reduce the environmental pollution,resulting great economic and social benefit.
