Ikuno Plant edition
In this edition, we will introduce the town where Mitsubishi Materials’ Ikuno Plant is located. Ikuno Plant has long been responsible for tin smelting and the management and maintenance of closed mines.
Asago, situated in the north-central part of Hyogo Prefecture, is one of Japan’s most prominent mining towns. There are numerous spots in the area where you can feel the historical signifi- cance, such as the remains of Ikuno Silver Mine and the buildings of Ikuno Plant.

It is said that silver was produced at Ikuno Silver Mine as far back as 1,200 years ago. It flourished as a shogunate-controlled mine and supported the modern- ization of industries for many years. The mine was closed in 1973 and is now a popular tourist attraction.


As the mine formerly belonged to the Meiji government and the imperial family, the gate posts bear the chrysanthemum crest.

About Ikuno Plant
Ikuno Mine, which was sold to Mitsubishi Goshi Kaisha by the Meiji government, is the origin of Ikuno Plant. The former mercury mixing facility, which now serves as the office for Ikuno Plant, was originally constructed in the early Meiji period to extract silver from ore. The historical brick structure has been certified as a Heritage of Industrial Modernization site by the Ministry of Economy, Trade and Industry. In 2017, it became one of the cultural assets that make up The Ban- tan Silver Mine Carriage Road / Ore Mining Road.

Management and maintenance of closed mines
The wastewater from the mine contains heavy metals, and Ikuno Plant is responsible for treating this water to clean it. We will continue to protect the natural environment around the mine.


So you’ve been working with the local mines for many years.
Tin smelting
Crude tin is produced by dry smelting tin scraps generated in the industrial sector. Subsequently, it is refined through processes such as electrolytic refining to achieve high- purity tin. Currently, the tin smelting business is managed by our group company, Materials Eco-Refining Co., Ltd.

There are a variety of other industrial heritage sites nearby.

These trolley tracks were used from the Taisho era (1912-1926). At the time, they played an important role in the local indus- try by connecting the mine to the station.
