Review of organic binders for iron ore concentrate agglomeration …
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich 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 …

A Detailed Look at Iron Ore Agglomeration
Iron Ore Agglomeration Tests. All lab tests are designed around the distinct qualities of each material, and thus the sample's characteristics should be acknowledged prior to testing. Overall, iron ore is: Heavy. Abrasive. Dusty / easily wind-blown. Varying in composition (some samples contain more clay than others).

Novel Binders and Methods for Agglomeration of Ore
Agglomeration of ore into coarse, porous masses achieves this even distribution of fluids by preventing fine particles from migrating and clogging the spaces and channels between the larger ore particles. Binders are critically necessary to produce agglomerates that will not break down during processing.
