New copper smelting and recycling process with “O-SR” Process, which is combined newly installed Mitsubishi Process S-furnace with the existing reverberatory furnaces and PS-converters has put into operation in December 2007. S-furnace has shown excellent performance since the start of operation. It is proven that S furnace has high adaptability with other processes. S-furnace which is directly connected to two reverberatory furnaces by launders, is solely used for copper concentrate smelting and reverberatory furnaces are dedicated to slag/matte separation and to treat combustible waste materials such as shredder dust (SD) generated from automobile, electrical home appliance and vending machine. After introducing of O-SR Process, amount of treated copper concentrates and combustible waste materials was increased. Furthermore, consumption of fossil fuel and generating CO2 was dramatically decreased at reverberatory furnaces. As a result, now Onahama Smelter & Refinery was revived as one of the most competitive copper smelter in the world by the combination of new technology and existing process.
