Three Core Businesses
Our mineral resource business, where we undertake mine development and operation in consideration of the environment and society. Our smelting and refining business, where we create high-quality metal materials from mining resources. And our materials business, where we add to these metal materials the new value that the times demand. While working to ensure organic collaboration among these three businesses, we provide advanced materials to shape the future.
