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 ...

For the primary separation, a Magnetic Separator (typically an Induced Magnetic Roll or Rare Earth Roll Separator) removes magnetically-susceptible para and ferro magnetic minerals (e.g. ilmenite, garnet, monazite). The secondary electrostatic separation focuses on separating the remaining minerals (e.g. zircon sand, silica and rutile).
