Dowa's zinc business

The DOWA Group was founded in 1884 when it received a grant from the Japanese government to purchase the Kosaka Mine in Akita Prefecture.
The Kosaka Mine subsequently became one of Japan's leading copper mines, contributing to the advancement of modern Japanese industries.
Today, inheriting the rich experience and technology cultivated in mining and smelting operations, we look towards a sustainable future, offering environmentally conscious products and services.
DOWA is recognized both domestically and internationally as a pioneer of the Recycling-oriented business model. For further details on this business model deployed by the DOWA Group, please view the DOWA HOLDINGS website.

The zinc business also plays a part in this business model. The DOWA Group owns two mines in Mexico to stably procure zinc ore/concentrates, while in recent years, it has been increasing the proportion of recycling materials. AKITA ZINC CO., LTD., the core of zinc business of the DOWA Group, is Japan's largest zinc smelter, and boasts the world's highest recovery efficiency of valuable metals through its unique and unrivaled technology called as "the Hematite Process".
And it has gained recognition as a smelter that does not generate waste, contributing to resource circulation and reducing environmental impact.
