Abstract (en)

[origin: EP1411135A1] Accelerating the separation of a granular metallic iron from slag. Production of a granular metallic iron comprising reducing and melting a raw material lump composed of an iron oxide containing material and a carbonaceous reducing agent, a solid mixture of the granular metallic iron formed by the above reduction and melting and a by-produced slag is quenched to thereby accelerate the separation of the granular metallic iron from the by-produced slag. The method can be used for producing a metallic iron being satisfactorily freed of slag and having an improved purity of iron.
