Abstract

The effect of fine particles on the storage stability of CWM has been investigated, and the method to improve the stability has also been studied. The stability of CWM is considered to depend upon the amount of fine particles present in the slurries, and it improves with an increase in the amount of fine particles. The characteristic parameters in the particle size distributions and slurry rheology are correlated with the stability of CWM.
