Mining Grade CMC is a carboxymethyl cellulose product used in mineral processing as a pellet binder, flotation inhibitor, and slurry dispersant. It helps improve pellet formation, wet and dry pellet strength, moisture control, pellet size uniformity, and metallurgical performance. In flotation systems, it can work as a silicate gangue inhibitor and assist in copper-lead separation control.

Carboxymethyl cellulose (CMC) serves important roles in the mining industry as a pellet binder and flotation inhibitor. It is a key component in the binder used for shaping mineral dust, and this binder is crucial for the production of pellets. CMC enhances the properties of wet, dry, and calcined pellets.
Its effective binding and pellet-forming capabilities result in green pellets with superior anti-knock performance, high compressive strength, and excellent drop resistance. Furthermore, CMC can elevate the grade of the pellets. In the flotation process, CMC acts as an adjusting agent, serving as a silicate gangue inhibitor that helps control lead during the separation of copper and lead. It is also sometimes used as a dispersant for mineral slurries.
Applications in Pellet Production
1. Excellent pellet formation and water control properties.
2. Converts pellets from hydrophilic to hydrophobic.
3. Delivers good dispersibility and high strength in wet pellets.
4. Ensures no distortion of pellets.
5. Provides strong mechanical strength in dry pellets.
6. Increases the compressive strength of pellets.
7. Exhibits high cracking temperatures, effectively controlling and releasing moisture within the pellets.
8. Achieves a homogeneous pellet size distribution.
9. Produces a smooth surface on the pellets.
10. Enhances metallurgical performance.
Applications in Flotation
1. Demonstrates good water solubility and strong inhibiting capabilities.
2. Improves the grade of finished ore and enhances specifications in ore selection.
3. Reduces the need for additional agents, thereby decreasing raw material consumption.
4. Primarily functions as a silicate gangue inhibitor, controlling lead in the separation of copper and lead, and occasionally works as a dispersant for slimes.
