    摘要： In a method for manufacturing potassium chloride with a K.sub.2 O content of 55 wt. % from the fine salt resulting from the decomposition of carnallite, n-alkyl amine salts are used as conditioning agents, and flotation media containing magnesium and potassium chloride are used to separate this fine decomposition salt in an initial flotation stage into a grain size fraction of 0.315. After the conditioning, this residue is again floated and the potassium chloride comes to the surface as a second pre-concentrate. Then the potassium chloride is separated from the mixture of the two pre-concentrates, without any further conditioning, in another flotation stage, and collected.

    摘要： A carnallite-containing crude salt is separated into a carnallite fraction, a sylvite fraction and an abandonable residue by grinding the salt to an average particle size of about 1.5 mm., conditioning the particles in a conventional manner with from 5-300 g/t of a conventional conditioning agent adjusting the relative humidity of the conditioned particles to 5-25%, and subjecting the resulting particles to electrostatic separation in two stages, wherein in the first stage the particles are subjected to a high voltage electric field having a field length of 0.4 to 1.2 m to separate a carnallite fraction by imparting to the carnallite fraction a high sidewards velocity relative to the initial downward velocity upon entering the field, thereby causing deflection of the carnallite away from a middlings fraction, and wherein in the second stage the first stage middling fracton is subjected to a second high voltage electric field having a field length of 1.5 to 2.5 m to f or m a sylvite fraction, a second middlings fraction which also has a high sidewards velocity imparted thereto relative to the initial downward velocity upon entry into the second field thereby causing deflection of the sylvite fraction away from and an abandonable residue which has a sidewards velocity imparted thereto opposite in direction to the sidewards velocity of the sylvite for deflection therefrom and from the second middlings fraction.

    摘要： 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.
