Beschreibung
Zusammenfassung:	Provided is a method for co-producing iodine and salt by use of underground brine containing iodine salt and sodium chloride. The method is a method to produce iodine and salt in parallel including a series of steps including: an iodine acquisition step; a collecting step for obtaining concentrated brine by simultaneously concentrating iodine salt and sodium chloride by using an electrodialysis device; and a roasting step for obtaining salt. The present invention encompasses various aspects in terms of the order of performing the iodine acquisition step, the collecting step, and the roasting step, which are included in the series of steps.
