Understanding Coagulation & Flocculation in Slurries

Efficient slurry dewatering is key to many mining and mineral processing operations, and two important processes involved are coagulation and flocculation.

These processes help transform fine, colloidally stable particles into larger agglomerated clusters that can settle more easily—improving overflow water clarity and enhancing thickening performance.

In this video, we demonstrate how polymers such as flocculants and coagulants interact with a diluted kimberlite slurry. You’ll see the difference between a slurry that remains dispersed and one that has been treated to promote particle agglomeration and settling.

Whether you’re looking to optimise reagent usage or better understand the science behind slurry dewatering, this demonstration provides a clear and practical look at the fundamentals of coagulation and flocculation.
