ABSTRACT:
A process for recovering alkali values from trona ore by partially dissolving trona in a first dissolving solution to form a first feed liquor and undissolved trona. The first feed liquor is cooled and sodium carbonate decahydrate is precipitated. The sodium carbonate decahydrate is recovered from the resultant first mother liquor that is returned as the first dissolving solution. The undissolved trona is further dissolved in a second dissolving solution to form a second feed liquor. The second feed liquor is preferably carbonated to convert sodium carbonate into sodium bicarbonate, and cooled to precipitate sodium bicarbonate. The sodium bicarbonate is recovered from the resultant second mother liquor that is returned as the second dissolving solution.
