How to Recover Hematite & Chromite Fines by Wet Magnetic
Apr 23, 2018· 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.
