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 .
Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.
In iron ore pelletizing Imerys bentonite is used as a binder for the formation of iron ore pellets. Pellets are balls produced from iron ore or concentrates and are used as feed material for iron making. Imerys bentonite adds significant value to the pelletizing process and the quality of the final product.
Bentonites unique properties have become a cornerstone of several applications: Binder in Iron Ore Pelletizing. Bentonite is the most commonly employed binder in the iron ore pelletizing, or balling process used in the production of steel. The importance of iron ore pelletizing has been on the rise in recent years as high grade sources of iron ore diminish, buyer preferences change, and producers
