Selective removal of metal contaminants from scrap iron oxide products was accomplished using a combined pelletization- chloridization process. Contaminants form volatile chloride compounds during the pellet-induration cycle. Pellet copper, zinc and lead levels, initially 0.43, 1.44 and 0.10 percent, were reduced to 0.08, 0.13 and 0.001 percent, respectively, while undergoing induration.
