The said process of chlorizing calcination treats multi-metallic lean tin complex feedstock to undergo high temp. reduction in rotary kiln. First, chlorizing agent and reduction agent are added to the made-up raw material, and after the procedures of mixing, sphericizing and drying it is sent to the rotary kiln for chlorizing calcination. The raw material mixture used in this process contains tin 1.2-2% only, tin, lead and other non-ferreous metals totalling to 5%. Under weak reduction atmosphere and 1000-1050 deg.C, valuable metals of Sn,Pb etc. sublimate and enrich thems in collected precipitates or collected solution, and then recovered respectively, while iron remains in spherical aggregate used as raw material for iron-steel smelting. |
