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.
