Production of sodium carbonate from solution mine brine
Frint et al., in Pat. No. 5,262,134, disclose a process for producing soda ash from a solution mine brine containing sodium carbonate and sodium bicarbonate by heating the brine to between 90#176; C. and 115#176; C. to evaporate water, convert sodium bicarbonate to sodium carbonate, and to drive off the resulting carbon dioxide therefrom until the concentration of sodium carbonate and sodium
