Abstract：The optimal utilization of the convert dust (mud) was proposed based on the dust composition, and the collocation usage of the BF dust and convert dust (mud) was studied on aspects of pelletizing and reduction. The viscidity and hardening effect in CO2 atmosphere of free CaO in convert dust was utilized in pelletizing process, and the strength of pellets without binder regent addition could meet the requirements of production. The reduction of pellets composed of converter dust (mud) and BF dust which was used as the carbon source were carried out, and the removal ratio of zinc was over 95% when the reduction temperature was higher than 1 250 ℃. The reduction degree of iron was higher than 80% with further enhancement of temperature to 1 280 ℃, which was over 95% in most cases. It offered an efficient method for the usage of the BF dust and converter dust (mud).
