Abstract | A method for recovery of salts comprises providing (210) of an initial aqueous solution comprising ions of Na, K, Cl and optionally Ca or a material which when brought in contact with water forms an initial aqueous solution comprising ions of Na, K, Cl and optionally Ca. The start material is treated (230) into an enriched aqueous solution having a concentration of CaCl2 of at least 15% by weight. The treatment (230) comprises at least one of reduction of water content and addition of Ca. The treatment (230) generates a solid mix of Na Cl and KCl. The solid mix of NaCl and KCl is separated (235) from the enriched aqueous solution, giving a depleted aqueous solution comprising ions of Ca and Cl as main dissolved substances. An arrangement for recovery of salts is also disclosed. |
