Abstract

A method of carrying out the process of the parent Specification is characterized by acidifying for instance with sulphuric acid, but preferably with phosphoric or hydrochloric acid, the mother liquor resulting from the separation of microcosmic salt prior to the crystallization of the mixture of potassium and ammonium chlorides (potazote). By this means, potazote is obtained free from phosphoric acid. In carrying out the process cyclically, phosphoric acid and ammonia, replaced in part, if desired, by mono-, di-, or triammonium phosphate, are added to the mother liquor from the separation of potazote until it contains one molecule of phosphoric acid to two molecules of ammonia, and the solution cooled to allow of separation of microcosmic salt. Sylvinite and phosphoric acid, the amount of the latter being about 15 per cent of the acid used in the process, are added to the mother liquor, and potazote is then separated from the cooled solution. The products are employed as fertilizers.ALSO:A method of carrying out the process of the parent Specification is characterized by acidifying for instance with sulphuric acid, but preferably with phosphoric or hydrochloric acid, the mother liquor resulting from the separation of microcosmic salt prior to the crystallization of the mixture of potassium and ammonium chlorides (potazote).
