METHOD FOR ACCELERATING SEPARATION OF GRANULAR METALLIC IRON FROM SLAG

摘要

A method for accelerating the separation of a granular metallic iron from slag, characterized in that, in a method for the 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 a improved purity of iron.
