Document Type and Number:
WIPO Patent Application WO/2011/155417
Kind Code:
A1
Abstract:
Disclosed is a granular metal production method that further increases granular metal productivity, wherein agglomerates containing a metal oxide and a carbonaceous reducing agent are heated to reduce and melt the metal oxide contained in the agglomerates and produce granular metal. Specifically disclosed is a production method for granular metal wherein agglomerates containing the metal oxide and the carbonaceous reducing agent is supplied onto the hearth of a traveling reduction melting furnace and are heated to reduce and melt the metal oxide and the resultant granular metal is cooled and then discharged to the outside of the furnace and recovered. Agglomerates of an average diameter of 17.5 mm or greater are supplied onto the hearth when heating with a spreading density for agglomerates on the hearth of 0.5 or greater.
