Optimizing The Performance Of The Rer Magnetic Separator

ABSTRACT Feed fractionation of a silica sand sample to a rare earth roll separator RER magnetic separator was found to be much more favorable for separation than the whole batch. The performance of the separator depends on both the size and the size distribution of the feed. The correlation between the different size fractions of the feed, e.g., 0.6 0.106, 0.6 0.211, and 0.211 ...
