  Antimony trioxide is a white-colored powder that is, like tin and bismuth, a byproduct of lead smelting.

Main products（Chemical Products）

• Chemical Products Business（zinc oxide as well as lead oxide and zinc sulfate, which we are the only company to manufacture in Japan）

  

  Main products（Chemical Products）

  We manufacture and sell zinc oxide as well as lead oxide and zinc sulfate, which we are the only company to manufacture in Japan. Zinc oxide is used as a vulcanizing accelerator to strengthen rubber products. Lead oxide meanwhile is used as a vinyl chloride stabilizer, in paints and in electronic materials such as ceramic condensers. Zinc sulfate is used as a raw material in fabrics, paper, animal feed and health food products.

Copper & Precious MetalsDiv.

We provide materials that form the cornerstone of industry, including copper and precious metals. We also help to create a more recycling-oriented society through our nonferrous and precious metal recycling operations. Which include recovering and recycling usable metal components from waste products.

Mineral Resources Division

The origin of our company goes back to 1874 when the Mitsui Clan began operation of the Kamioka Mines in Gifu prefecture, Japan. Resource development technologies developed over the history of our company have helped us successfully develop numerous mines in Japan and overseas. They have also being applied to resource recycling and underground energy resource development.
While Japan debates its strategy for securing resources, we are harnessing our technologies to contribute to the efficient use of global resources.

Main products（Mineral Resources）

• Mineral Resources(Zinc concentrate, Lead–Silver concentrate, Copper concentrate)

  

  Main products（Mineral Resources）
