Red Mud Flocculants Used in the Bayer Process SpringerLink

Abstract Flocculation and separation of red mud is an integral part of the Bayer process Over the latter half of the 20 th century flocculant technology dramatically changed from natural starches to use of rationally designed polymers Many of these advancements were due to the introduction of liquid or emulsion based flocculants which enabled elaborate post-reaction chemistry to be...
