Copper: Metal copper production is roughly the same as in 1985 at 943,000 tonnes, while electrical wire consumption is about 930,000 tonnes for 430,000 tonnes of copper (tubes, rods, wires, plates, strips) , Less than the part imported from abroad, transferred to 157,000 tons of inventory, and the remaining for copper alloy and towels and so on. In addition to enhancing rationalization and energy saving, the smelting factories of Japanese non-ferrous companies focus on the enhancement of equipment transformation and technological transformation in their production operations. ▲ Sumitomo Metal Mining Company East to smelter: flash furnace waste heat boiler superheater was originally heavy oil
