bentonite in iron ore processing

  • Effects of bentonite fiber formation in iron ore

    7/1/2002· 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, resulting in significant cost savings while producing higher quality, lower silica pellets.

  • Process Development Essential to Bentonite Processing

    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 look to operate more sustainably.

  • Iron Ore Pelletizing Process: An Overview

    Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.
