2005-4-1  Hydrometallurgical processing of a Vietnamese chromite ore was attained through oxidative leaching in highly concentrated KOH aqueous solution in the presence of compressed air at 300 °C under atmospheric pressure.Followed by diluting with fresh water or dilute KOH aqueous solution, the leaching process achieved the salting-out of hexavalent chromium in the form of K 2 CrO 4 crystal due to

The soda-ash roasting of chromite ore processing residue

Sodium chromate is produced via the soda-ash roasting of chromite ore with sodium carbonate. After the reaction, nearly 15 pct of the chromium oxide remains unreacted and ends up in the waste stream, for landfills. In recent years, the concern over environmental pollution from hexavalent chromium (Cr6+) from the waste residue has become a major problem for the chromium chemical industry. The
