How to Recover Chromite

 · To improve chromite recovery with the Humphrey''s spiral, a sample of Emma Bell ore was ball mill ground to minus 100 mesh and then processed with the spiral (table 11). This procedure improved the concentrate grade (splits 1 and 2) to 21.6 pct Cr2O3 from 17 pct for the minus 28-mesh test (see table 9), but did not decrease the grade in the tailings (splits 5, 6, and 7) below 13 pct.

DETERMINATION OF FEO IN CHROMITE ORE – MSK

The chromite ore is normally having a composition of FeCr2O4 which may be written as FeO.Cr2O3. In some ore Fe is partially replaced by Mg as (Fe, Mg) Cr2O4. The ore may have Fe in other form besides being present in the spinel. An accurate determination of FeO content is extremely important in chromite ores and refractories made with them.
