PROCESS FOR RECOVERING VALUABLE METALS FROM WASTES PRODUCED DURING THE MANUFACTURE AND THE PROCESSING OF STAINLESS STEEL

摘要

The present invention provides a method for recovering valuable metals from waste generated during the manufacture and processing of stainless steel, which can improve the recovery rate and quality of valuable metal elements and a continuous operation rate by improving the operation stability of a subsequent smelting reduction electric arc furnace while improving the quality of crude zinc oxide recovered when reducing roasting various waste generated during the manufacture and processing of stainless steel in a preliminary reducing furnace. The method of the present invention comprises the steps of: washing stainless steel dust; manufacturing a briquette; recovering crude zinc oxide; and recovering valuable metal components.
