Minerals, silicon metal, activated carbon, and other products


We import various raw materials mainly from China—one of the major mineral producing countries in the world—as well as Brazil, India, and other countries.

Activated carbon

We import coconut shell-based activated carbon from the Philippines and coal-based activated carbon from China.

Mill scale

Mill scale is ferric oxide that is generated in the metal rolling process. It is recovered and recycled for use as iron powder material or is sintered and used as material for the production of pig iron.
