The main disadvantage of bentonite and other binders based on silicate minerals is that they add silica to the fin- ished pellet. Since the purpose of iron ore processing is, inter.

Iron Ore Pelletizing Bentonite | Imerys

The need for iron ore pellets is directly connected to the steel production industry. Through the pelletizing process, iron ore fines are converted into spherical pellets, which are then suitable as feed material in blast furnaces for pig iron production. Imerys' bentonite acts as the binding agent in the production of iron ore pellets.

study on the improvement of preheating and roasting . - Springer Link

With the gradual depletion of iron ore resources, low-grade iron ore resources must be upgraded by the means of mineral processing. Then, the iron concentrate must be pelletized to be used in industrial production [1,2]. During pelletizing, binders must be added to improve the strength of pellets, of which bentonite was.

Additionally Peridur can be used to achieve other positive effects in iron ore processing, such as improving iron recovery during the beneficiation and concentration. When Peridur is used as a bentonite replacement in the pelletization process, silica specifications of the iron ore concentrate can be made less restrictive.

Taconite - Wikipedia

In the late 19th and early 20th centuries, the United States was mining such an abundance of iron ore of high quality that taconite was considered an uneconomic waste product. By the end of World War II, however, much of the high-grade iron ore in the United States had been exhausted. Taconite became valued as a new.

Advances in Alternative Binders for Iron Ore Pellets - SAO/NASA ADS

The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing. Bentonite adds unwanted silica to the final concentrated iron ore product. Excess silica from bentonite addition has been calculated to consume approximately 2.4 MJ of additional energy during the production.
