2001-6-1  The initial stage of the process was the conversion of insoluble chromite ore into water-soluble chromate. Roasting a mixture of chrome-iron ore, with sodium carbonate and lime at 1100°C for several hours produced sodium chromate. The lime acted as a mechanical separator allowing oxygen to react with the chromite and sodium carbonate (1).
