  • Effects of bentonite fiber formation in iron ore ...

    Jul 01, 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.
