Mining Grade CMC Sodium Carboxymethyl Cellulose in Floating Selection

CMC is used in mining industry as pellet binder and floating selection inhibitor. CMC is a component of the binder for mineral dust shaping, and the binder is an indispensable ingredient in pellet forming. It can improve the character of wet pellet, dry pellet and calcinated pellet. Due to its good binding property and pellet forming property, the green pellet with CMC has excellent antiknock performance, high compressive strength and dropping resistance. It can also increase the grade of pellet. CMC is adjusting agent in floating selection process, it is used as silicate gangue inhibitor, controlling the lead in copper and lead separating, sometimes it is used as dispersant for mineral mud.

Applications in Pellet
1. Good pellet forming and water controlling property.
2. Good dispersibility, the intensity of the wet pellet is high.
3. No distortion of pellet.
4. Dry pellet has good intensity.
5. The cracking temperature is high, strong in controlling and releasing the water inside the pellet.
6. The pellet measurements distribute well.
7. The surface of the pellet is smooth.
8. Good metallurgy performance.

Applications in Floating Selection
1. Good water-solubility and inhibiting ability.
2. Improve the grade of finished ore and get better specifications in ore selection.
3. Reduce the use of other agents, cut down the consumption of raw materials.
