Abstract

The invention relates to a magnetic separation device, which comprises a magnetic body, a nonmagnetic sheath and a first container, wherein the magnetic body is provided with a first magnetic pole and a second magnetic pole, the nonmagnetic sheath is movably sheathed on the first magnetic pole, the first container is used for containing mixture suspension liquid of magnetic particles and nonmagnetic particles, and when the first magnetic pole sheathed with the nonmagnetic sheath is placed into the mixture suspension liquid for absorbing the magnetic particles, the second magnetic pole is positioned above the liquid level of the mixture suspension liquid. The magnetic separation device provided by the invention can be used for simply and fast realize the magnetic separation on the magnetic particles, and the magnetic particle loss caused by accidental magnetic particle bringing out by the magnetic body is effectively prevented. When a magnetic iron content measuring method of the magnetic separation device provided by the invention is adopted, the analysis error caused by magnetic particle bringing by the magnetic body can be avoided, and higher precision and higher accuracy are realized.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation, and in particular relates to a magnetic separation device and a magnetic separation method using the magnetic separation device, wherein the magnetic separation device is a small-sized magnetic separation device suitable for analysis experiments. Background technique [0002] Magnetic separation is a beneficiation method that uses the magnetic difference between minerals to separate different minerals in an inhomogeneous magnetic field. After the ore to be selected enters the separation space of the magnetic separation equipment, it is affected by the combined action of magnetic force and mechanical force, and moves along different paths, and the ore pulp is intercepted separately to obtain different products. [0003] Magnetic analyzers such as magnetic separation tubes, magnetic analyzers, induction roller magnetic separators, and strong magnetic mineral separators are commonly used...
