Chapter 6 Bentonite Applications
Pelletizing iron ore. Sodium bentonite is used to pelletize iron ore (Devaney, 1956). Finely pulverized iron ore concentrates are pelletized into marble-sized spheres about 2.5 cm in diameter for ease of handling and shipping and to produce a superior furnace feed. The sodium bentonite constitutes about 0.5 wt.% of the pelletized ore.

Advantages of Dry Triboelectric Separation of Minerals
The counter current flow of the separating particles and continual triboelectric charging by carbon-mineral collisions provides for a multistage separation and results in excellent purity and recovery in a single-pass unit. The high belt speed also enables very high throughputs, up to 40 tons per hour on a single separator.
