Procedure

contacting said ore deposit with an aqueous 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 sodium bicarbonate enriched feed brine to precipitate crystals in subsequent step c) would result in the formation of sodium bicarbonate or sodium sesquicarbonate crystals instead of or in addition to sodium carbonate decahydrate crystals;

Workup

  1. customto precipitate crystals in subsequent step c)
