Process for obtaining schoenite by direct treatment of kainite mineral containing sodium chloride as impurities, characterized in that the kainite ore, ground with a granulometry of the order of 0.05 to 0.1 mm, is gradually added, while stirring in moderation, to the sulfate mother liquors obtained by treating schoenite with water, in order to separate potassium sulphate, thus obtaining a crystalline phase consisting of a mixture of schoenite crystals and sodium chloride in which the sodium chloride crystals have maintained their original grinding size while that the schoenite crystals have a much larger size, of the order of 0.1 to 0.75 mm, and the separation of the schoenite from the mixture with sodium chloride is carried out, therefore, by means of a volumetric classification, thus obtaining the schoenite in the portion that has the largest granulometry.
