Mining Grade CMC (Sodium Carboxymethyl Cellulose)


CMC isused in mining industry as pellet binder and floating selection inhibitor. CMCis a component of the binder for mineral dust shaping, and the binder is anindispensable ingredient in pellet forming. It can improve the character of wetpellet, dry pellet and calcinated pellet. Due to its good binding property andpellet forming property, the green pellet with CMC has excellent antiknockperformance, high compressive strength and dropping resistance. It can alsoincrease the grade of pellet. CMC is adjusting agent in floating selectionprocess, it is used as silicate gangue inhibitor, controlling the lead incopper 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 andreleasing 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 specificationsin ore selection.

3. Reduce the use of other agents, cut down the consumption of rawmaterials.
