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.
