Pelletisation of iron ore is one of the key uses for bentonite clays in refractories without coal. The bentonite is employed as a flux, making firing a less energy intensive process, and allows for the oxidation of magnetite to hematite ahead of the blast furnace(16). Pelletisation makes for a more efficient melting process due to a larger surface area to volume ratio, and takes place in a

Bentonite is either white or yellowish in color and has a wax-like, soil-like, or grease-like luster that depends on iron content. Bentonite can be classified as Na-bentonite, natural bleaching earth, and Ca-bentonite on the basis of exchangeable cation type and content, as well as the size of the montmorillonite layer charge.

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 pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI).

01.07.2002· The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate. Bentonite is a significant cost item in iron ore pelletization, and also contributes undesirable amounts of silica to the finished pellets. If the binding effectiveness of bentonite is increased, it will be possible to reduce the bentonite dosage
