As the most promising technology, the rotary hearth furnace (RHF) process has developed very rapidly in recently decade. Herein, combined with experimental research and engineering application for RHF process on the metallurgical dusts containing zinc and iron, the influence of carbon ratio, reduction temperature and reduction time on dezincification and metallization rate were investigated. The results showed that the dezincification and metallization rate could reach more than 90% and 70% respectively, when the carbon oxygen mole ratio was 1.0, reduction temperature was 1250 ℃ and reduction time was 25min. It is provable for the dezincification and reutilization of metallurgical dusts containing zinc and iron by RHF process.
