A method for concentrating salts according to an embodiment of the present invention includes the following steps: analyzing components of seawater or salt water; calculating the density at which each precipitate is separated by the analysis of the components; separating a first product at a first density while removing water from the seawater or salt water; and separating a second product at a second density higher than the first density while removing water from the seawater or salt water. The present invention aims to provide the method for concentrating salts from the seawater or salt water, which does not need a separate salt separation process and can obtain other types of salts such as KCl and the like in a more pure form in addition to NaCl. 본 발명의 일 실시예에 따른 염의 농축 방법은 해수 또는 염수의 성분을 분석하는 단계, 상기 성분 분석으로 각 침전물이 구분되는 밀도를 산출하는 단계, 상기 해수 또는 염수의 물을 제거하면서 제1 밀도에서 제1 산출물을 분리하는 단계. 상기 해수 또는 염수의 물을 제거하면서 제1 밀도보다 높은 제2 밀도에서 제2 산출물을 분리하는 단계를 포함한다.
