Abstract: The environment will be polluted for direct discharge of concentrator wastewaters with refractory organic flotation reagents, and the reuse of untreated wastewater in the grinding or flotation process will affect the separation indexed. Advanced oxidation technologies(AOPs) are one of promising water treatment technologies. In order to promote the application of advanced oxidation technologies in such wastewater treatment, the research progress of degradation efficiency and process principles of organic reagents by ozone and its combined oxidation technology, Fenton oxidation, photochemical oxidation, photocatalytic oxidation, electrocatalytic oxidation and persulfate oxidation for degrading reagents were introduced systematically. And the application prospect of advanced oxidation technology for the treatment of mineral processing wastewater was predicted.
