ABSTRACT:
In a method of producing iron by direct reduction of the ore, compaction into agglomerates and fusion, where the ore is reduced by a gaseous process with pre-reduction to monoxide FeO at 1000.degree. C., followed by a final reduction at 700.degree. C. The resultant powder is compacted into agglomerates and dumped, in successive loads after each pour, into an induction melting furnace and melted by contact and mixing with a preexistent charge of liquid metal. An amount equivalent to the newly-melted charge is poured into a refining ladle, after skimming off the slag.
