| titleOfInvention | Method for synchronously solidifying and stabilizing arsenic sulfide slag and recycling sulfur resources |
| abstract | Synchronization is disclosed hereinA method for solidifying and stabilizing arsenic sulfide slag and recovering sulfur resources mainly adopts a hydrothermal method, arsenic slag is quickly converted into arsenic sodium alunite by introducing a mineralizer aluminum sulfate, conversion conditions are optimized, and the long-term stability of the arsenic sodium alunite is evaluated. Nammite is an extremely stable mineral with a general chemical formula of NaAl 3 (SO 4 ) 2 (OH) 6 Using arsenate (AsO) 4 3‑ ) With sulfate radicals (SO) in the structure of sodalite 4 2‑ ) Substitution of the same similarities between them to form arsenic sodium alunite solid solution (NaAl) 3 (SO 4 ) 2‑x (AsO 4 ) x (OH) 6 ) Thereby realizing the solidification and stabilization of the arsenic. The experimental result shows that x in the arsenic sodium alunite solid solution can reach 0.154, the mass fraction of arsenic is 2.85 percent, and the volume reduction of waste residue is more than 60 percent; the recovery rate of sulfur reaches more than 90%, and the purity of sulfur exceeds 95%. The arsenic leaching toxicity of the arsenic sodium alunite solid solution is evaluated, and the result shows that the leaching concentration of arsenic is 0.1-0.5 mg/L, the requirement of dangerous waste stockpiling is met, and the technology is economical and effective in stabilizing arsenic slag. |
