Procedure

In further embodiments, the removed solution can be enriched in sodium bicarbonate and sodium carbonate. Further, the removed solution can be treated to form sodium bicarbonate, sodium sesquicarbonate, sodium carbonate monohydrate or anhydrous sodium carbonate. In particular, the removed solution can be treated to form sodium bicarbonate by carbonating the removed solution. Alternatively, the removed solution can be treated to form sodium sesquicarbonate. The step of treating can include a step selected from the group consisting of cooling, evaporative crystallization and combinations thereof. Sodium carbonate monohydrate can be recovered from the removed solution and prior to recovering sodium carbonate monohydrate, the solution can be treated by a step selected from fortification, steam stripping, evaporation, the hydroxide process, and the sodium carbonate decahydrate process.
