ABSTRACT In steel industry and in mines, a significant amount of ultrafines 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 ultrafines materials. Pelletizing can use ...

Review of organic binders for iron ore concentrate agglomeration Springer

Lowgrade iron ores are finely ground and processed to recover ironbearing minerals. However, the ironrich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets, but it is ...
