    摘要： A process for manufacturing an aqueous sodium chloride solution and the use of such solution for the manufacturing of crude sodium bicarbonate from SOLVAY ammonia process or for the manufacturing of soda ash, comprising the steps of: a) dispersing a first solid material comprising sodium chloride, sodium carbonate, and sodium sulfate, and a second solid material comprising calcium chloride in an aqueous liquid to produce an aqueous medium; b) subjecting the aqueous medium to clarification to produce a clarified aqueous medium; and c) recovering the clarified aqueous medium as aqueous sodium chloride solution; wherein a weight L/S ratio between the weight of the aqueous liquid used to produce the aqueous medium and the total weight of the first solid material and the second solid material is in the range of from 0.7 to 3.5.
