Abstract: Flotation is an important part in the process of mineral processing, in whichvarious flotation agents need to be added to separate the useful minerals from the pulp. Most flotation agents are complex and difficult to degrade, which means the flotation wastewater contains a large number of flotation agents.Ordinary wastewater treatment process on the residual flotation agent of removal effect is not satisfactory. As an efficient means of wastewater treatment, advanced oxidation technology, the advanced oxidation technology has a good effect on the degradation of residual flotation reagents.This paper briefly introduces the concept ofmineral processing agentand the origin, composition, characteristics and harm ofmineral processingwastewater, applicationand researchof degradationof mineral processingwastewaterfor advanced oxidation are discussedat home and abroad; The degradation mechanism of beneficiation wastewater by advanced oxidation technology such as Fenton oxidation, photochemical oxidation, sonochemical oxidation and ozone oxidation was discussed. The application prospect of advanced oxidation technology to degrade ore dressing waste water was prospected.
