      <abstract xml:lang="ru">
        <p>Метод флотационного обогащения, совершивший в последние годы полный переворот в использовании полезных ископаемых, пока, по-видимому, не применялся при разделении растворимых в воде солей на составные компоненты, так как никаких литературных данных по этому вопросу не имеется. Приложение же весьма рационального способа флотации, хотя бы к отдельному случаю, для упрощения и сокращения длительного и громоздкого способа фракционированной кристал­лизации, дало бы толчок к дальнейшему развитию исследований в этой области, результаты которых могли бы сильно упростить технологический процесс при разделении солей.</p>

        <p>The flotation enrichment method, which has made a complete revolution in the use of minerals in recent years, apparently has not yet been used to separate water-soluble salts into their component components, since there is no literature data on this issue. The application of a very rational flotation method, at least to a separate case, to simplify and shorten the long and cumbersome method of fractionated crystallization, would give impetus to the further development of research in this area, the results of which could greatly simplify the technological process for the separation of salts.</p>
