In view of the existing problems such as large amount of slag and zinc loss in the neutralization and arsenic removal process of atmospheric lime oxide leachate of zinc oxide fume at present, in this paper, research on pressurized oxidation and arsenic removal is carried out to diminish weaknesses of the existing process. The results indicate that under better pressure oxidation and neutralization conditions, the arsenic removal rate is up to 99.1%, the slag content is 16.16g/L, the zinc content is down to 3.32%, the arsenic content is up to 6.83%, and the slag content and zinc loss are more than 60% and 80% lower than normal pressure, respectively.
