    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.

    This invention relates to the enrichment of minerals by separation in an electric field. The closest in technical essence and the achieved result to the proposed method is electrostatic enrichment of raw potassium salts, including grinding and conditioning the source material by treating it with 5–5% relative humidity with air, two stages between oppositely charged electrodes in an electric separator free fall on valuable components, intermediate and residue lj. The disadvantage of this method is the low efficiency of the separation process in the presence of carnallite in the starting material. The closest in technical essence and the achieved result to the proposed is a device for electrostatic enrichment of raw potassium salts, including vertically located electrodes, a loading device, a device for outputting the separated component and receivers of separation products 2. A disadvantage of the known device is the low efficiency of the separation process availability, in the source material of carnallite. The purpose of the invention is to increase the efficiency of the enrichment process of a material containing carnallite by sequentially separating valuable components. This goal is achieved in that, according to the method of electrostatic enrichment of raw potassium salts, including grinding and conditioning of a 5–25% relative humidity, two-stage separation between oppositely charged electrodes in a free-fall electric separator, the intermediate product and the residue rejected to the positive SeH component, containing carnallite concentrate, is taken away from the plot.

The electrode is a valuable component, containing the sylvic concentrate, selected by the next additional drop area 1.5–2.5 m long, and the unshaken HEPITT / il ncvjM sloped intermediate noonwr is returned to the beginning of the additional drop site. Additional In the device for electrostatic enrichment of raw potassium salts, including a vertically positioned "G ° ° ® fixture. k§K eG | „“; The dividing electrode is made of separate, located one above the other parts, and the negative electrode has a length equal to the sum of the individual parts of the positive electrode, while the device for outputting the separated material component is installed between the parts of the positive the device, and the device is equipped with a funnel made of a non-conductive material installed in the interelectrode space, with the upper edge of the funnel located at the lower edge of the upper part of the positive a and its lower edge is located at the middle portion of the positive electrode izhney. In addition, the electrodes can be made in the form of tapes or pipes. The method is carried out as follows. The source material containing potassium salts, carnallite and sylvin, is crushed to a particle size of 0.5-1.5 mm, conditioned, treated with air with a humidity of 5-25% and exposed to it by an electrostatic field of high intensity with free fall of the material between the vertically spaced electrodes opposite polarity in the free fall electrical separator. Since the canalite ob-U has a high specific charge, it is deflected in the electrostatic field at a large angle, and, when it falls, a section of the working zone with a height of 0.4-1.2 m reaches a positively charged electrode, where carnallite unloads to the appropriate receiver. Sylvin, having the same sign of charge with carnallite, but having a lower specific charge value, deviates in an electrostatic field by a small angle and reaches. After the 3T3rtJ, the sylvin is unloaded into the corresponding receiver. Product without rejecting the V ° receiver. , “- ..“ ..- g, .. ““ ith to any electrode, directing the cleaning to the site of the slave ® zone, located at a height of 1, The drawing shows a device that implements a method of electrostatic enrichment of raw potash ores. The device contains the upper and lower parts 1 and 2 of the electrodomes positive polarity and negative electrode 3 opposite to them, the feeder 4 adaptive 5 for outputting the separated component, deflected to the positive electrode 1 and containing carnallite. The box 6 with deflecting devices into the receivers 9, 11 for separation products, the electrode 3 having a length equal to the sum of the lead parts 1 and 2 of the electrode put, -,.

However, all electrodes can be made either in the form of tubes or in the form of flax The electrodes 1 and 2 are connected to a high voltage source, and the electrode 3 is grounded The proposed device works as follows: Pre-conditioned and air-treated 5-25% moisture material containing sylvin, carnallite and potassium salts, is fed to the working zone with a feeder 4 the separator of the torus, formed by electrodes of opposite polarity, where the material drops freely. Particles of karyallite, which have a large surface charge specificity, are sharply deflected in the electrostatic field of the separator and, at a height of 0.4-1.2. m, reach the electrode 1, where they are unloaded by the device 5 into the carnallite receiver. The sylvite particles, which have a smaller specific surface amplitude, are weakly deflected by the field created by electrodes 1 and 3, are fed into the funnel 6, where they are charged, and upon exit from the funnel 6. The particles that are not deflected by the electrostatic field enter the receiver 10, and the particles deflected to the negative polarity electrode 3 are unloaded in P) point 11. Thus, the proposed method and device for its implementation will increase the efficiency of the process. Yeni material containing carnallite.
