| Abstract: |
| This paper reviews the sources of arsenic-containing contaminant in non-ferrous metals industry and their harmless treatment methods, and analyzes the advantages of encapsulated arsenic (cement curing and glass curing) and mineral solid arsenic (calcium, aluminum, magnesium, and sulfide precipitation methods). Disadvantages and limitations, focusing on the research status of synthetic methods and leaching stability for safe treatment of arsenic in the form of scorodite. The analysis shows that the crystalline scorodite synthesis is the basis for the safe disposal of arsenic in the form of scorodite. Stability is the key. Further reducing the supersaturation of the solution to achieve the synthesis of large-size and high-stability scorodite is the development direction. |
