The upgraded ore and iron hydrate are subsequently separated by means of cyclones, elutriation, tabling, flotation and so on. Prereduced ferruginous ores of chromite, ilmenite and phosphate minerals are upgraded in a single stage process utilising ferrous sulphate or ferrous chloride leach solutions.

The main component of the chromium ore is chromite FeCr 2 O 4. The ores extensively dispersed in natural deposits and generally contaminated with Mg, Si, Al, and O. The chromium metal commercially separated by oxidizing chromite ore to Cr 2 O 3, then the metal is attained by heating the Cr 2 O 3 in the presence of Al or Si [5,6]. detail

Jul 20, 2017The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.

The Bureau of Mines, U.S. Department of the Interior, devised a flotation technique for upgrading chromite in chromium ores and gravity concentrates. The technique consisted of cationic flotation of chromite from a slime-free pulp acidified to ph 2.5 Or lower using h2so4 modifier. Flotation results showed that ore containing serpentine as the primary gangue
