Abstract
A method for agglomerating finely divided iron oxide material consisting substantially of hematite and/or magnetite, preferably concentrates enriched with iron ore, and for hardening the agglomerates thus formed, characterized in that the fine material is agglomerated by rolling, micronodulizing or other granulation methods, and is given a suitable particle size distribution for fluidization purposes, and is transferred to a fluidized bed furnace in which the bed is heated by supplying gaseous or liquid fuel and gas containing free oxygen, or by means of hot gases, after which the main part of the material is extracted from the bed in agglomerated and hardened state.
