Abstract: Approximately 75% of gold ore processing plants in the world apply cyanidation leaching method, which produces a large amount of cyanidation tailings. It causes serious waste of resources and threatens the ecological environment and human health. Focusing on the present situation of cyanidation tailings over the world, this paper analyses the decyanidation technology and application. Simultaneously, this paper emphatically analyzes the recycling technology of gold, silver, copper, lead, zinc, iron, tellurium and other valuable metals in cyanidation tailings. Eventually, this paper summarizes the research progress of decyanation method of cyaniding tailings and recycling of valuable metals, and provides a reference for the harmless and recycling of cyaniding tailings.
