ABSTRACT:
A process for the production and recovery of crystalline sodium sesquicarbonate and of crystalline sodium carbonate monohydrate from aqueous liquors containing sodium carbonate and sodium bicarbonate. The crystalline products may optionally be heated or calcined to produce soda ash. The process is particularly suited for the recovery of soda ash from aqueous minewater streams obtained from solution mining of subterranean trona ore deposits.
