  • Method for the recovery of iron units from flue dust generated in a steel making process
    Patent number: 4407672
    Abstract: A method for the recovery of iron units contained in flue dust generated in a steel making process is provided comprising the steps of collecting the dust generated in the steel making process and agglomerating the collected dust into stable green ball pellets in a pelletizing apparatus. The green ball pellets are loaded into an electric arc furnace charging bucket by placing the pellets at or near the bottom of the charging bucket and covering the pellets with other steel making material. The charging bucket containing the pellets and other steel making material is charged into the electric arc furnace only after the furnace has been previously charged with steel making material which does not contain such pellets.
