Organic binders present a relatively small number of unique binding options but provide an extraordinary amount of flexibility in how to apply them. ... the ability to maintain the dispersion of the iron ore during the binding process, and limited water ...
The goals stemming from the final reduction process are drawn back through the pelletization process to present a clear rationale for why each material can be used to control the pellet quality. Major inorganic binders such as bentonite, colemanite, and lime are examined along with less commonly used alternatives.
The pelletizing process, where the crude ore from the mine is upgraded, involves several steps, including grinding, balling, and induration; see Figure 1 to the left. In the grate-kiln induration process []—see Figure 1 to the right—the sintering is mainly taking place in a rotary kiln, where the pellets increase their strength and metallurgical properties.
However CaO and Ca(OH) 2 are quite common in pellets anyways, as it is often added as a flux to the iron ore concentrate. Thus, in iron ore pelletization, class C and class F fly-ashes may both undergo pozzolanic reactions. Fly-ashes which do not meet ASTM C618 may still be useful as pellet binders, so long as they are pozzolanic.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
