The invention relates to agriculture, namely to a method for utilization of polymineral brines of Carpathian region and preparation of potassium fertilizers. A method for the utilization of polymineral brines is claimed, comprising staged evaporation in vacuum-evaporation device and crystallizing of salts, and 30-40 % of sodium chloride is extracted by low-temperature to 90 °C evaporation through fine and repeated grinding in scrub chamber with S-like sprayers in gaseous carrier flow with following cooling and further crystallizing of sodium chloride and decantation of mother solution as potash-magnesium fertilizer. |
