Method for the conversion of chromite ore to sodium chromate |
| abstract |
A method of producing sodium chromate from chromite ore which involves mixing the ore with sodium carbonate and a refractory diluent, pelleting the mixture at a temperature of at least 36* C. using a pelleting liquid which may be water or water containing dissolved substances, drying and roasting the pellets under oxidizing conditions, then disintegrating and extracting the pellets to obtain an aqueous solution of sodium chromate. The practice of pelleting the mix at a temperature at least above that at which sodium carbonate decahydrate normally forms, provides pellets of improved strength to withstand handling and roasting in a furnace. |
