| Remarks | 1981 -
Replaced the carbon cooler at the cooling tower with tge acid coolers 1984 - Increased the SO2 blower rotation speed 1986 - Boosted the circulation pumps at the drying and absorption towers 1987 - Constructed the SO3 Cooler at the converter Bed 1 1994 - Boosted the SO2 blower pressure, Pre-converter added 1995 - Acid cooler replacement 2000 - WESP expansion 2006 - Cesium promoted catalyst used in Bed 4. DCS installed. 201? - SO3 cooler after bed 3 replaced with a boiler (53 MPa). SO3 cooler at pre-converter replaced with a superheater (350oC). More steam generated leading to more power. At the Tamano Smelter operated by Hibi Kyodo Smelting Co., Ltd., the annual capacity for refined copper production reached 260,000 tons in 2006, thanks to investments in the introduction of a slag cleaning furnace and the permanent cathode method. |

| General |
Furukawa Co. Ltd. The history of the Metals Division dates back to 1875, when our company was founded to start operations at the Kusakura Copper Mine (Niigata). In 1877, this business was expanded to the Ashio Copper Mine (Tochigi). As for a copper smelting technology, we established the Furukawa/Outokumpu type flash smelting technology, which is highly-acclaimed as a top level technology. In 1954, we purchased a flash smelting technology from Outokumpu in Finland and subsequently added our own modifications to it for the above technology. The Furukawa/Outokump type flash smelting technology is widely used by copper smelting companies at home and abroad. Against the background of this technological capability, we import copper ore, and produce and supply gold, silver, sulfuric acid and others as well as copper. We have the optimal production system in place by entrusting Onahama Smelting & Refining Co., Ltd., Hibi Kyodo Smelting Co., Ltd. and other smelting companies, in which Furukawa Metals & Resources Co., Ltd. invests, with smelting operations. |
