Procedure

contacting said ore with an aqueous solvent solution containing sodium carbonate to produce a sodium bicarbonate enriched feed brine in which the sodium bicarbonate and sodium carbonate content is such that cooling of such enriched feed brine to precipitate crystals would result in formation of sodium bicarbonate or sodium sesquicarbonate crystals instead of or in addition to sodium carbonate decahydrate crystals, said enriched brine having a total alkalinity of from about 11% to less than about 20%;
