Chromite Procurement By Magnetic Seperation Method

Chromite Procurement By Magnetic Seperation Method

Oct 29, 2019 Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals. To address this, dry magnetic separation is an alternative approach to separate these iron-bearing gangue minerals from the chromite.

To use a chromite ore directly as an input for smelting FeCr, the ore generally needs to contain than 49 wt Cr2O3 Chromite ores with Cr2O3 content lower than 49 wt need to be further upconcentrated by mineral processing techniques (eg, magnetic separation, gravity separation, flotation, etc) [13].
