The underflow of each vat is heated before passing to the next one since the dissolution of sodium nitrate is endothermic. Sodium nitrate therefore dissolves preferentially. The product solution obtained after leaching contains 450 g/L of sodium nitrate and is cooled to 5 10 deg C in heat exchangers and with ammonia refrigerating equipment.
