Flotation and Granulation of Sodium Carboxymethyl Cellulose in Mining Industry

2023-01-02

LUDE CHEM® Sodium Carboxymethylcellulose CMC is an organic depressant commonly used in the physicochemical mineral flotation process to separate non-valuable (gangster) minerals from valuable minerals.


1. Flotation principle of sodium carboxymethyl cellulose in mining industry:

Sodium carboxymethyl cellulose acts as a depressant, during mineral flotation, Sodium carboxymethyl cellulose CMC inhibits unwanted mineral particles by adsorbing them, making them hydrophilic and therefore non-floatable, but valuable The minerals are adsorbed by agents called collectors, making them hydrophobic so they can float to the surface via air bubbles.

2. Principle of granulation and pelletization of sodium carboxymethyl cellulose in mining industry:

LUDE CHEM® sodium carboxymethyl cellulose CMC can be used as an organic binder for iron ore pelletization, and it is a substitute for bentonite used in transition.

The advantage of using LUDE CHEM® CMC over bentonite is not only a reduced dosage or silica content on the granules, but also a positive impact on the environment and energy consumption in granule production.
