ABSTRACT:
A process for recovery of alkali values from trona in which trona is dissolved, the sodium carbonate in the feed solution is converted to sodium bicarbonate by introducing carbon dioxide, sodium bicarbonate is crystallized and separated from a mother liquor, and sodium bicarbonate in the mother liquor is converted to sodium carbonate by introducing air to form a recirculating dissolving solution which is used to dissolve the trona.
