Plenty of cyanide wastewater is produced by gold mines every year.Its detoxification and recycling as resources is a serious challenge that all gold enterprises face and a major problem that must be solved as soon as possible.The advantages and disadvantages of purification technology and recycling process for cyanide wastewater are ela-borated.The purification technology includes natural degradation,bio-oxidation,alkaline chlorination method,SO₂/air method,hydrogen peroxide method,ozone oxidation method,and so on.Recycling processes include the AVR method,activated carbon adsorption method,resin adsorption method,solvent extraction method,liquid membrane method,and so on.The research hopes that it can provide technical references for cyanide wastewater purification and recycling,and eventually that sustainable development of mines is realized.
