     Metal sulfide tailings by ore dressing in metal mines are one of main sources of combination pollution of （ acid water＋） heavy metals.In recent years international research tends to investigate the chemical specia-tion, stability/mobility and environmental effect of heavy metals in the tailings by the method of Dold procedure especially designed for the extraction of elements in sulfide tailings.Domestical research mainly focuses on the test analysis and experimental simulation of the chemical speciation and mobility of heavy metals in the tailings , but considers less the multiple factors affecting the occurrence state of heavy metals in the tailings; and less re-search on the mechanism of combination pollution of heavy metals in the tailings situated in the carbonate/Karst environment landscape area.The carbonate area in Nanling region of China is one of the main districts rich in nonferrous metal minerals, but frequent combination pollutions of heavy metals.In this area, to clarify the mechanism of retention and mobility of heavy metals in the carbonate-rich sulfide tailings, and investigate on the occurrence state of heavy metals in the tailings , is significant for the prevention and pollution treatment from the tailings in theory and practice , as well as for resource recycling.
