METHOD OF PRODUCTION OF NON-MAGNETIC ORES CONTAINING NON-MAGNETIC PARTICLES OF A SUSPENSION MASS FLOW

FIELD: mining.SUBSTANCE: to determine the efficiency of at least one step of the recovery method, at least one indicator indicating the amount of the proportion of ore particles or magnetic particles in the separator feed stream and/or separator flux and/or separator of residual stream is determined. An index indicating the amount of the proportion of ore particles and/or magnetic particles is determined for at least two streams, on the basis of this index, in particular, after comparing the parameters relating to each of the flows indicating the proportion of ore particles and/or magnetic particles, at least one operating parameter of the mixing device and/or magnetic separator is set. The index is compared with at least one limit value indicating the minimum or maximum concentration of ore particles in the separator concentrate stream and/or in the residual stream of the separator. Depending on the result of the comparison, at least one operating parameter of the mixing device and/or magnetic separator is set. The method is carried out by means of a device comprising at least one mixing device for mixing mass flow with magnetic particles, at least one supply device for supplying a mass flow to at least one magnetic separator, at least one separation device for separating ore particles from the separator concentrate stream, at least one recording device for determining at least one index indicative of the proportion of ore particles or magnetic particles in the means of at least one control and/or control device, into the separator stream and/or in the separator concentrate stream and/or in the residual separator stream. The control and/or control device comprises at least one computer-readable software. The software, depending on a certain metric, is designed to control and/or adjust the mixing device and/or the magnetic separator and/or the separation device.EFFECT: increase of extraction efficiency of non-magnetic ores.16 cl, 1 dwg Предложенная группа изобретений относится к извлечению немагнитных руд из содержащего немагнитные частицы руды суспензионного массового потока.
