Abstract:Using the thermodynamic calculation software designed by the author, the thermodynamic calculation and analysis of the new process of liquid phase oxidation of chromite show that the new process holds strong reacting tendency, high exothermic quantity and wide reaction conditions at low temperature. In comparison with the conventional high-temperature roasting process for present chromate production using sodium carbonate as reaction media, the process of liquid phase oxidation of chromite in the molten salt of sodium hydroxide is much more advantageous.
Key words: chromite; molten salt; liquid phase oxidation; thermodynamics
