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

Fluorite,Coke,Anthracite,Deoxidizing material (aluminum),Heat insulating material

Some of subsidiary materials used for the steelmaking and casting

Fluorite,Deoxidizing material (aluminum),Silica sand,Anthracite,Coke,Sulfide iron ore,Zircon sand,Heat insulating material,Ferrosilicon


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.


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.

Raw materials for ceramics

Mullite,Raw bauxite,SiC,Calcined kaolin
