The invention relates to the electrostatic separation of ground crude potassium salts containing kieserite. The separation method is characterized in that the ground crude potassium salt is intensively mixed with a conditioning agent containing a combination of an aromatic carboxylic acid or its derivatives, an ammonium salt of an aromatic carboxylic acid, as well as an unbranched fatty alcohol having a chain length of C10 to C15, and subsequently triboelectrically charged at a relative humidity of 1-10%, and separated into a crude kieserite fraction and a crude potassium fraction by means of an electrostatic separation method. By means of use of the method, the kieserite yield is increased, and the selectivity of a subsequent treatment by means of flotation is increased.
