Title:
METHOD FOR PRODUCING METALLIC IRON
Document Type and Number:
WIPO Patent Application WO/2014/021473
Kind Code:
A1
Abstract:
The first purpose of the present invention is to provide a method for producing metallic iron, whereby, in the production of metallic iron by heating an agglomerate, which comprises an iron oxide-containing material and a carbonaceous reducing agent, in a movable hearth type heating furnace, metallic iron can be efficiently collected from a reduced product containing metallic iron and a slag, said reduced product being obtained by heating the agglomerate.
The method for producing metallic iron according to the first embodiment of the present invention comprises: a step for forming an agglomerate of a mixture which comprises an iron oxide-containing material and a carbonaceous reducing agent; a step for introducing the obtained agglomerate into a movable hearth type heating furnace and reducing the same by heating; a step for milling a reduced product containing metallic iron and a slag, said reduced product being discharged from the movable hearth type heating furnace, using an impact mill; and a step for selecting and collecting the metallic iron using a separator.
