Embodiment

[0014] Electromagnetic magnetizer is used. The premagnet is composed of a cylindrical electromagnetic coil wound on a copper tube. Direct current is fed into the coil to form a magnetic field with a strength of 400×80A / m.

[0015] Before the pulp enters the weak magnetic field sorting equipment, it first passes through the copper tube of the magnetizer, and the residence time in the copper tube is 0.2-10 seconds to magnetize the pulp to 15-30×10 -6 rice 3 / kg and then enter the weak magnetic field magnetic separator for separation.

Abstract

A beneficiation method for magnetic ore belongs to the technical field of beneficiation and is characterized in that magnetic ore slurry is magnetized by a pre-magnetic device till the susceptibility reaches 15 to 30 multiplied by 10<-6>m<3> per kilogram and then sent into a low-intensity (magnetic) separator to carry out separation. By adopting the method of the invention, the grade of concentrated ore can be increased; the grade of tail ore can be reduced and the recovery rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a mineral processing method of strong magnetic mineral particles. Background technique [0002] The effect of sorting strong magnetic ores depends not only on the difference in the specific magnetic susceptibility of the constituent minerals, but also on the remanence and coercive force of the constituent minerals. The mineral processing of the prior art is to directly process the ore particles through a weak magnetic field magnetic separator for mineral processing. -6 rice 3 / kg), the effect of magnetic separation is very good; but for ore particles with weak magnetism, the effect of magnetic separation is slightly worse. Contents of the invention [0003] Aiming at the problems in the prior art, the invention provides a magnetic separation method more suitable for ore particles with less magnetic properties, thereby improving the grade of magnetically...
