ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultra-fines materials.

Mar 19, 2008 · Iron ore, its beneficiation and agglomeration - as required for iron and steel industry: A. Iron Ore: A naturally occurring mineral from which iron (Fe) metal is extracted in various forms viz Hot metal/ DRI etc.. B. Types of Ore: Two major varieties used for iron making are Haematite Ore ( containing Ferric Oxide - Fe2O3) and Magnetite Ore (containing Ferro-Ferric Oxide – Fe3O4).

Novel Binders and Methods for Agglomeration of Ore

Similarly, production of primary iron from iron ore is critically dependent on agglomeration. Concentration of iron oxide minerals requires grinding to very fine particle sizes, frequently smaller than 25 µm, in order to liberate and separate the iron oxides from the silicate gangue.
