ABSTRACT:
A method of producing sodium bicarbonate having a high degree of purity and obtaining a net reduction in effluent waste water, as compared to prior processes, when starting from trona ore is disclosed. The process entails utilizing the waste-water effluent stream from the conversion of trona ore to sodium carbonate as the feed for the conversion of sodium carbonate to sodium bicarbonate.
