Copper Smelting and Precious Metal Refining Equipment

From the Edo Era (1603 to 1868) Sumitomo's Besshi copper has supported Japanese industry. Toyo Smelter and Refinery of Sumitomo Metal Mining Co., Ltd. has inherited this history, and is a major center for copper smelting. Toyo Smelter and Refinery is a world top class copper smelter, and currently has the world's largest production capacity. Moreover, it is a clean and environment friendly smelter plant. We undertake the engineering work for all production equipment at Toyo Smelter and Refinery , and we are contributing to higher levels of efficiency and labor saving.
In 2003, the precious metal refinery process was changed to the PMEX (Precious Metals Solvent Extraction & Ion Exchange) process, proprietary technology developed by Sumitomo Metal Mining. We undertake the engineering work for all PMEX production equipment.
