RECYCLING METHOD OF ELECTRIC FURNACE DUST

摘要

PURPOSE: A recycling method of electric furnace dust is provided to reduce a process cost required to the reclamation of dust, and to prevent the contamination of underground water caused in the reclamation of dust. CONSTITUTION: In the recycling method of electric furnace dust generated in a minimal process, the electric furnace dust containing iron oxide of more than 60 percent by weight and zinc oxide of less than 20 percent by weight and solid carbon is mixed according to an appropriate compounding ratio and then formed into pellets. The formed pellets are input into an electric furnace by using a scrap input hopper so that iron content in the electric furnace dust can be completely withdrawn.
