Use of Boron Compounds as Binders in Iron Ore Pelletization

iron-making processes such as the blast furnace or the DR-plant. Hence, an agglomeration technique should be applied to fine concentrate. The most commonly employed one is pelletizing in iron ore industry. In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates.

Pelletizing - an overview | ScienceDirect Topics

Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a "green" pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.
