Abstract

The polymer flocculants and dewatering additives have been applied to separation of Red Mud for thirty years. In recent years, it is pointed out that the additives is related to the presence of other ions. The experimental results show that the effect of mud dewatering and mud compaction will affect the production capacity and purity of product. The potential of using water absorbing polymer or synthetic dispersant to change the rheological property of the slurry is also summarized in the end. The combination of these effects, with the new bio polymer to improve the primary pour into the washing bath of the overflow liquid clarity and recovery of sodium hydroxide is also researched.
