Abstract
Crude potash salt is conditioned for separation into its components by means of an electrostatic field by grinding the salt to disintegration and contacting the ground salt with a conditioning agent, such as salicylic acid, which has been converted to the gaseous state, such that the conditioning agent draws up onto the surfaces of the salt crystals by absorption. The quantity of the conditioning agent employed is adjusted by varying the evaporation temperature and/or by varying the volume of heated air and/or inert gas, serving as a carrier material.
