METHOD FOR PRODUCING GRANULAR METAL
Document Type and Number:
WIPO Patent Application WO/2002/103064
Kind Code:
A1
Abstract:
A method for producing a granular metal wherein a raw material composed of a material containing a metal oxide and a carbonaceous reducing agent is heated to reduce the metal oxide in the raw material, and the formed metal is further molten by heating and then is coagulated while separating it from the slag by−produced, characterized in that the raw material further comprises a coagulation accelerator for the by−produced slug. The method allows the production of a granular metal having a high metal purity which has a large granule diameter, resulting in its excellent transportability and handleability, in high yield with good productivity.
