gold mine tailing extraction technology

Composition, Harm and Resource Utilization Technology of Gold
Starting from the composition and harm of gold tailings, this paper summarizes two directions for the resource utilization of gold tailings. One is to recover valuable components from tailings by roasting, leaching and flotation. The other is to use tailings to process
