摘要： PROBLEM TO BE SOLVED: To provide a treatment process which can solve problems accompanying thermal reduction of high-Ca dust containing valuable metals for recovering the valuable metals, such as erosion of a furnace bottom refractory and decrease in rate of reduction caused by the high Ca-content and reduction in recovery rate of the valuable metals accompanying these. SOLUTION: When thermally reducing the dust containing metal components and ≥15 mass% Ca component calculated in terms of CaO (based on dry weight), a Ca-diluting material is added to the dust to adjust the Ca content calculated in terms of CaO to ≤14 mass% before performing thermal reduction. This inhibits erosion of the furnace bottom refractory caused by slag leaching and enables efficient thermal reduction. COPYRIGHT: (C)2004,JPO
