While interacting with the water, bentonite clay expands and becomes sticky. This property allows to effectively use it as a binder for the production of pellets from iron ore concentrate (wet, crushed iron ore that has been beneficiated). Pellets are used in blast-furnace redistribution and electrometallurgical production.
