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.
