    It is seen that the recovery of Cr2O3 increases with decreasing particle size. The grade of the magnetic concentrate slightly depends on the particle size. Such a dependence is due to the distribution of Cr2O3 in various sizes of the feed it is evident that the recovery can be greatly enhanced at a magnetic induction greater than 0.43 T.
