A manufacturing method of deep seawater-derived natural mineral salt is provided to manufacture mineral water or mineral salt selectively containing minerals through the electrodialysis, electrodegradation, reverse osmosis and crystallization due to solubility difference from the deep seawater. The manufacturing method of the deep seawater-derived natural mineral salt comprises the steps of: (A) collecting and passing the deep seawater through the filter; (B) subjecting the filtered deep seawater to electrodialysis through the monovalent cation selective exchange membrane and the monovalent anion selective exchange membrane; (C) mixing mineral salt water obtained from the step (B) with the potassium mineral water in a volume ratio of 1 : 0.5 ~ 1.5; (D) evaporating the mixed mineral water of the step (C) in an evaporator, wherein the potassium mineral water is prepared by (A1) passing the deep seawater through the filter, (B1) subjecting the filtered deep seawater to electrodialysis through the monovalent cation selective exchange membrane and the monovalent anion selective exchange membrane, and (C1) evaporating the mineral salt water obtained from the step (B1) in an evaporator and removing the sodium salt segregated. |
