ABSTRACT:
Iron oxide powder, e.g., ore, is reduced in a CO/N.sub.2 atmosphere at a temperature between 750.degree. to 1200.degree. C., whereby prior to the onset of precipitation of metallic iron the content of H.sub.2 is limited to 15% (vol) of the CO content, and SO.sub.2, H.sub.2 S, COS or another suitable gaseous sulphur compound is developed or maintained in the reducing atmosphere at a range from 0.0005 to 0.1% (vol), preferably 0.001 to 0.01% (vol) in relation to the CO content.
