| Abstract: |
| It is substantiated in the study that the pollution caused by reagent for beneficiation in the condition of photodegradation will cause secondary pollutant and secondary pollutant chain which transfers to regionality and globalism.In the condition of photodegradation,aerofloat 25~# forms biphenyl and condensed aromatics which transfers to global pollution with POPs;collectors containing sulfur(xanthate,SN_9 and benzothiazole) can release CS_2 in the atmosphere and cause artificial sulfur pollution.It is ultimately caused that global climatic change is influenced and formation of acid rain is aggravated.When collectors containing sulfur degrade,lots of micromolecule organics with functional groups are produced.These micromolecule organics become a part of the mine complex pollution and extend the transferring and hazardous areas of complex pollution caused by reagent for beneficiation and reagent for beneficiation with heavy metal. |
