| Abstract Scope |
In Kosaka Smelting and Refining Co., Ltd., tin inlet increases rapidly from around 2008, because of TSL furnace starting up and raw materials change from ores to E-scraps. With tin increase negatively affected on lead productivity, Lead Smelting Section reinforced tin removal process from lead. In this process, tin is oxidized into the form of dross and separated from molten crude lead.
In addition, new processes recovering tin metal from the dross were installed. These processes contain both pyrometallurgical (reduction) and hydrometallurgical (electro winning) sections. Currently tin metal becomes one of the main products of Kosaka.
In this paper, the tin removal and recovery processes are described. |
