Abstract

Настоящее изобретение относится к системе и способу для сухого обогащения руды, содержащей оксиды железа, которая включает мелкие и сверхмелкие частицы и находится в отвалах для хвостов и рудных хвостах с низким содержанием этих оксидов, причем система содержит сушилку (9), выполняющую сушку за счет ввода горячего воздуха, со средствами механического перемешивания и валами, снабженными лопатками (9.2), для дезагрегации и перемещения материала в горизонтальном и вертикальном направлениях; группу воздушных классификаторов, не жестко соединенных с выпуском сушилки, которые выполняют классификацию мелких и сверхмелких частиц железной руды по заранее определенным гранулометрическим диапазонам; и магнитные сепараторы (13, 16, 19) с магнитными роликами (32, 42, 47), установленными в виде каскада и изготовленными из редкоземельных магнитов, имеющих низкую и/или высокую магнитную индукцию, причем магнитные ролики установлены под заранее определенным углом наклона.The present invention relates to a system and method for the dry beneficiation of ore containing iron oxides, which includes fine and ultrafine particles and is located in tailings for tailings and ore tailings with a low content of these oxides, and the system contains a dryer (9) that performs drying by entering hot air, with means of mechanical mixing and the shaft supplied with shovels (9.2), for disaggregation and movement of material in the horizontal and vertical directions; a group of air classifiers that are not rigidly connected with the release of the dryer, which carry out the classification of fine and ultrafine particles of iron ore according to predetermined particle size ranges; and magnetic separators (13, 16, 19) with magnetic rollers (32, 42, 47) installed in the form of a cascade and made of rare-earth magnets having low and / or high magnetic induction, with magnetic rollers set at a predetermined angle of inclination.
