General Dowa Mining Co.,Ltd. combined with five non-ferrous metal refining companies established the Akita Zinc Co.,Ltd. in February 1971 to produce electrolytic Zinc. The refining plant is situated in a large-scale waterfront development.
Our Iijima Refinery is located on the waterfront district of Akita Bay in a favorable environment. It is one of the leading plants in the world, concentrating on the latest technologies, in a spacious site.
This factory was designed with full antipollution facilities.


The raw ore that is procured is processed by Akita Zinc Co., Ltd., and electrolytic zinc is produced. Dowa Metals & Mining Co., Ltd., has an 81% stake in Akita Zinc, which is its joint-consignment smelting subsidiary. Akita Zinc is Japan’s largest producer of electrolytic zinc, with an annual output of 200,000 tons, and is regarded as among the top zinc smelters in the world in terms of quality and productivity. The zinc bullion produced is converted to products that meet the needs of diverse customers by Akita Zinc Solutions Co., Ltd., which are then marketed by Zinc Excel Co., Ltd. An integrated business structure has been established that covers every phase from the mining of raw ore to the production and sale of finished goods.
