Abstract The cyanide-contained wastewater is difficult to be treated because of the characteristics of complex component, high salt content and high concentration of pollutants in gold hydrometallurgy. This study developed a literature review about the method for cyanide-containing wastewater treatment, analyzing on benefits, critical and challenges factors. Cyanide can be destroyed or recovered by different processes. This paper discusses the emerging methods for removing cyanide, particularly the application of combined process and new efficient methods. The progress of multi-process treatment of cyanide-contained wastewater desalination and zero discharge was summarized.
