Summary of Business

Main Products

Here are some of our products related to the manufacture of iron and steel, cast iron and ceramics.

Materials for steelmaking and casting

such as fluorite, coke, anthracite, deoxidizing marerials and heat insulating materials.
Some of subsidiary materials used for the steelmaking and casting
  • Fluorite

    China and Mexico are main production centers of fluorite. Japan imports fluorite for 100,000 tons a year. Fluorite is used mainly as solvent for steelmaking and raw material for fluoride. Since we started treating fluorite outputted from Hiraiwa Mine, Gifu Prefecture, in around 1950, fluorite has been one of our main products.

  • deoxidizing marerials(aluminum)

  • Silica sand

  • Anthracite

    China, Vietnam are main production centers of anthracite. Japan imports anthracite for 5,000,000 tons or more a year. We sell anthracite mainly as recarburizing material.

  • Coke

  • Pyrite

  • Zircon sand

  • Heat insulating material

  • Ferrosilicon
