| Abstract: |
| The residual beneficiation reagents from the mine wastewater are harmful to the aquatic organism, which could also result in the re-contamination of heavy metals in tailing impoundments. This research studied the degradation characteristics of several beneficiation reagents under natural sunlight and photocatalytic systems. As the result, butyl-xanthate was degraded easily by natrual light while dithiophosphate and GYB are refractory; pH values had different effects on different reagents; photocatalyst had very strong removal ability to all kinds of researched reagents, and could mineralize the N,P-containing reagents to NO3- and SO42-. |
