Abstract

HIGH SULFUR IRON ORE CONCENTRATES CAUSES SEVERAL PROBLEMS IN STEEL MAKING PROCESS AND HENCE AFFECT THE CONCENTRATE PRICE. ALSO ITS LEAD TO ENVIRONMENTAL ISSUES SUCH AS SULFUR DIOXIDE EMISSIONS DURING THE CONCENTRATE PELLETIZING PROCESS. THE CURRENT STUDY IS FOCUSED ON THE REMOVAL OF SULFUR FROM IRON ORE CONCENTRATE USING CHEMICAL LEACHING TECHNIQUE. MAGNETITE IRON ORE CONCENTRATE WERE CHOSEN FOR THE STUDY. LABORATORY RESULTS ARE PRESENTED HERE. THESE RESULTS SHOW THAT MORE THAN 90% OF THE TOTAL SULFUR CONTENT, CAN BE REMOVED FROM IRON ORE CONCENTRATE BY CHEMICAL LEACHING. THE BACKGROUND FOR THE PROCESS CONCEPT AND A SUMMARY OF THE RESULTS ARE PRESENTED BELOW. EFFECT OF SEVERAL PARAMETERS SUCH AS TEMPERATURE, PARTICLE SIZE ON SULFUR REMOVAL WAS STUDIED BY SERIES OF EXPERIMENTAL CONDITIONS. EXPERIMENTAL RESULTS DEMONSTRATE THAT THE SULFUR REMOVAL WAS ENHANCED WITH THE INCREASE IN TEMPERATURE AND INCREASING TEMPERATURE WAS MORE IMPORTANT IN SULFUR REMOVAL THAN DECREASING PARTICLE SIZE.
