To achieve the separation of arsenic and antimony from high-arsenic antimony-containing dust, a selective oxidation roasting process was employed with barium oxide as an antimony-fixing agent. The effects of oxygen partial pressure, roasting temperature, roasting time, and the dosage of antimony-fixing agent on the volatilization rates of arsenic and antimony from the dust were explored. The results indicate that with pure oxygen flow rate at 40 mL/min, addition of barium oxide at an amount of 2%, and roasting at 450 ℃ for 60 min, the volatilization rates of arsenic and antimony in the dust can reach 90.46% and 6.79%, respectively. It is shown that the volatile products contain 99.53% As2O3 and 0.26% Sb, thus effective separation of arsenic and antimony from high-arsenic antimony-contained dust antimony can be actualized.
