A method for sorting minerals, comprising: feed mineral aggregate and water into an inner cavity of a transversely arranged primary sorting barrel, a central axis of the primary sorting barrel being arranged along a transverse direction; drive the primary sorting barrel to rotate, and apply a magnetic field to the inner cavity of the sorting barrel at the same time; accurately sort ore pulp by means of a classifier; enable the selected minerals in the ore pulp to form magnetic aggregate and/or magnetic flux linkage in the processes of rising along with a barrel wall and dropping due to gravity under the actions of the magnetic field and the classifier; after the magnetic aggregate and/or magnetic flux linkage that are/is big enough are/is aggregated, the magnetic aggregate and/or magnetic flux linkage attach(es) to an inner wall of the primary sorting barrel and move(s) upwards all the way along with the rotation of the primary sorting barrel until reaching a blanking area located at the upper part of the inner cavity; and except the selected minerals, other materials in the ore pulp enter a tailings trough from the bottom of the inner cavity. |
