Document Type and Number:
WIPO Patent Application WO/2014/065240
Kind Code:
A1
Abstract:
Provided is a process for manufacturing reduced iron by heating agglomerates, said process being capable of enhancing the yield of reduced iron and thus improving the productivity thereof. A process for manufacturing reduced iron which includes a step for agglomerating a mixture that comprises an iron oxide source, a carbonaceous reducing agent and a melting point regulator and a step for heating the obtained agglomerates to reduce the iron oxide contained in the agglomerates, wherein the agglomerates contain at least 1 mass% of a silicate mineral having a solidus temperature of 1300ºC or lower.
