| Abstract: |
| With the gradual depletion of high quality ore, complicated ore containing arsenic was gradually being mined, and the production of arsenic residues increased continuously. As the toxicity of arsenic and arsenic compounds are quite strong, so how to effectively deal with arsenic residues to make it harmless become very urgent. TheSdetrimentSofSarsenic and the origin of arsenic-containing wastes are introduced, the present situation and existing problems of the processing is reviewed. Currently, major treatment methods forSthe resource utilization of arsenic residues include copper sulfate cementation process , Sferric sulfate leaching process, alkali leaching process etc. and the solidification-stabilization of arsenic residues include cementS solidification process,Scalcium salt stabilization process etc..But these methods have respective shortcomings, in order to effectively solve the problem of arsenic residues, stabilization arsenic by forming scorodite is the countermeasure of treatment arsenic residues. |
