pelletizing of iron ore Due to its water absorption capacity and colloidal property, bentonite is used as a binding additive to convert iron ore fines into 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 ...

Bentonite for iron-ore pelletizing 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).

In the production of iron ore concentrate pellets, binders are required to improve pellet green strength.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 …

Iron Ore Pelletizing Industries. Binders improve pellet green strength in the production of iron ore concentrate pellets. And the one that solves the purpose is Sodium Bentonite clay, which has higher water plate absorption along with superior Thermal Stability. Elements–Binder.

Iron ore pelletization is a critical aspect of the steel manufacturing process, providing a method to utilize fine iron ore particles and beneficiate lower grade ores, which enhances the overall output and efficiency of steel production processes. Pelletization involves converting iron ore fines into compact pellets, which are then used in blast furnaces or direct …

Organic binders have been used as alternative to bentonite in the iron ore pelletizing process mainly because it burns without leaving residue in the pellet. There are two main types of organic ...

Abstract: In this study, sodium, calcium, and mixed bentonite samples were used as binders in the pelletizing fine iron ore concentrate obtained from the Divrigi Iron Ore Concentration Plant in Turkey. In the pelletizing tests, sodium bentonite sample was used as received and after upgrading process.
