For indurated pellets, carboxymethyl cellulose (210.2 ± 1.88 kg/pellet) and sodium lignosulfonate (198.1 ± 2.49 kg/pellet) pellets were weaker than those of bentonite (250.4 ± 2.06 kg/pellet ...
A brief introduction to recent developments in iron ore pelletizing is provided in this chapter, including the world output of fired pellets, pellet production processes, …
16.1. Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources.
• The pressure resistance of pellets formed by activated calcium bentonite addition is much lower than the pellets formed with Sodium Bentonite. • Also, when Activated Calcium Bentonite is used as a binder alone, the wet pellet efficiency is also reduced. • Pellet Bentonite is specially prepared for Iron Ore Pelletizing.
Litter:Bentonite is used for litter, due to its advantage of absorbing refuse by forming clumps (which can be easily removed) leaving the remaining product intact for further use. Pelletizing: Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical ...
The microstructure of bentonite in wet and dry iron ore pellets, as well as in distilled water, was imaged by various imaging techniques (e.g., imaging at low voltage with monochromatic and decelerated beam or low loss backscattered electrons) and cryogenic methods (i.e., high pressure freezing and plunge freezing in liquid ethane). ...

Pelletizing iron ore. Sodium bentonite is used to pelletize iron ore (Devaney, 1956). Finely pulverized iron ore concentrates are pelletized into marble-sized spheres about 2.5 cm in diameter for ease of handling and shipping and to produce a superior furnace feed. The sodium bentonite constitutes about 0.5 wt.% of the …
