About Iron Ore Pelletizing (Balling) Pellets are a high-grade source of iron ore and are produced via a type of agitation agglomeration (wet granulation or tumble-growth agglomeration) known as pelletizing, and referred to in the iron ore sector as "balling."

Iron ore pelletizing is a two-step process. This begins with the formation of green pellets with the addition of a binder to improve agglomeration phenomena. Then it follows an induration process to obtain appropriate mechanical and metallurgical properties [7], [8], [9].

Since the iron ore concentrate, which has been comminuted to the flotation fineness, is neither transportable nor usable, it must be agglomerated. The growth agglomeration of iron ore concentrate in the pelletizing disc is therefore an indispensable part of iron ore processing. Is this method becoming more and more known/popular? And why?

Pelletizing, in ironmaking, is a process used to agglomerate iron ore concentrates with a granulometry <150 µm and low concentration of impurities.Iron ore concentrates are mixed with water, bentonite, and hydrated lime (cold agglomeration) and are treated in a rotary disk to form round agglomerates (green pellets) with sizes comprised within 10 and 20 mm in diameter.

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.
