Recent Zinc and Lead Smelting Operation at Kamioka Mining and Smelting Co., Ltd.

Abstract

Kamioka Mining and Smelting Co., Ltd. became independent of Mitsui Mining and Smelting Co., Ltd. in 1986. Kamioka’s metallurgical operation consists of zinc electrolytic winning, lead smelting and lead electrolytic refining. The company’s main products are electrolytic zinc, electrolytic lead, zinc alloy, silver, cadmium, bismuth and sulfuric acid. Our metallurgical operation developed together with the mining operation at Kamioka mine, but the raw materials at zinc plant and lead plant were changed due to the reducing of the mine products. The new technologies that we developed to change the raw materials and the power that is supplied from the hydropower plants are our advantages. We will make effort to survive in Japan with these advantages.
