This specification discloses a method for electrostatic separation of crude potassium salts into its components the separation process being of the type carried out at relative humidity of 2 - 30% in the presence of a conditioning agent. The method involves reduced requirements as to the amount of the conditioning agent. The process is characterized in that the ground potassium salt, comminuted to the required grain size, is brought into contact with a gaseous conditioning agent, so that the conditioning agent is held to the surfaces of the salt crystals by adsorption. The amount of the conditioning agents is adjusted by controlling the temperature of the gasifying (or vaporizing) air …
