Abstract

The invention discloses a kind of superconducting magnetic separation method that can improve trickle magnetic-particle yield, relate to sorting mineral technical field. Below magnetic separation equipment, be provided with at least one superconducting magnet, magnetic separation arranged on interior magnetic fine particle and produce an artificial gravity, thereby improve the separation performance of gravity treatment and flotation; So-called artificial gravity utilizes magnetic to produce an attraction consistent with mineral grain gravity, and equivalence has increased the weight of mineral grain; Superconducting magnet moves reciprocatingly below magnetic separation equipment, in the time that superconducting magnet moves to magnetic separation equipment below, due to the existence of high-intensity magnetic field, makes the fine particle in magnetic separation equipment be deposited to magnetic separation device bottom, and accumulates in the high-intensity magnetic field district in magnetic field; In the time that superconducting magnet moves to away from magnetic separation equipment below, because magnetic separation equipment is not in field regions, the magnetic-particle in magnetic separation equipment can be discharged smoothly. Can improve some mine, because of the mineral yield of trickle magnetic-particle when more.

Description

A kind of superconducting magnetic separation method that can improve trickle magnetic-particle yield
Technical field
The present invention relates to a kind of sorting mineral method, refer in particular to a kind of superconducting magnetic separation method that can improve trickle magnetic-particle yield.
Background technology
The prerequisite of magnetic separation magnetic mineral is that magnetic mineral must be monomer separation. The trickle magnetic-particle of normal conditions has been all monomer separation. But just because of trickle, gravity is little, conventional gravity treatment, method for floating are all helpless to it. In the time that employing sinks to the bottom material and is the flotation column of magnetic material, trickle magnetic-particle is easily mixed in foam and runs off, and the yield that how to improve this parts of fine micromagnetism particle is that the problem solving is urgently wished in some mine.
Summary of the invention
One object of the present invention is to propose a kind of superconducting magnetic separation method that can improve trickle magnetic-particle yield.
For achieving the above object, provide following technical scheme:
A kind of superconducting magnetic separation method that can improve trickle magnetic-particle yield, below magnetic separation equipment, be provided with at least one superconducting magnet, make to produce on the magnetic fine particle in magnetic separation equipment an artificial gravity, thereby improve the separation performance of gravity treatment and flotation; So-called artificial gravity utilizes magnetic to produce an attraction consistent with mineral grain gravity, and equivalence has increased the weight of mineral grain; Superconducting magnet moves reciprocatingly below magnetic separation equipment, in the time that superconducting magnet moves to magnetic separation equipment below, due to the existence of high-intensity magnetic field, makes the fine particle in magnetic separation equipment be deposited to magnetic separation device bottom, and accumulates in the high-intensity magnetic field district in magnetic field; In the time that superconducting magnet moves to away from magnetic separation equipment below, because magnetic separation equipment is not in field regions, the magnetic-particle in magnetic separation equipment can be discharged smoothly.
Further, described magnetic separation equipment comprises and sinks to the bottom the flotation column that material is magnetic material, it is characterized in that, described flotation column is at least one, is provided with at least one movably superconducting magnet below flotation column. Removable is that magnetic-particle in order to make to sink to the bottom can discharge when without magnetic field or downfield.
Preferably, the material of described flotation column is nonmagnetic substance.
Preferably, described flotation column is eight or multiple, is evenly distributed on same circumference; Be provided with flotation column support in flotation column bottom, below flotation column, be provided with superconducting magnet, bottom in superconducting magnet is provided with roller, the superconducting magnet supporting seat top of circumferential is provided with the toroidal cavity matching with roller, roller is arranged in groove, superconducting magnet supporting seat top is also provided with haulage gear, and haulage gear is connected with superconducting magnet outside. Haulage gear drags superconducting magnet and moves in a circle on superconducting magnet supporting seat.
Preferably, described superconducting magnet is the solenoid type superconducting magnet of heavy caliber, high-intensity magnetic field. Heavy caliber, high-intensity magnetic field can make sphere of action wide.
Beneficial effect of the present invention is:
Select a kind of flotation device, its material sinking to the bottom is magnetic mineral, select a kind of suitable flotation column, arrange in its bottom one movably, heavy caliber, high field superconducting magnet, make magnetic-particle comprise that fine particle all can be subject to the settling capacity (magnetic attracting force) of an extra gravity direction, because trickle magnetic-particle is subject to extra settling capacity (magnetic attracting force), therefore can improve some mine, because of the mineral yield of trickle magnetic-particle when more.
Brief description of the drawings
Fig. 1 is a kind of floatation equipment top view that can improve trickle magnetic-particle yield of the present invention;
Fig. 2 is A-A cutaway view in Fig. 1.
Wherein: 1, flotation column, 2, flotation column support, 3, superconducting magnet, 4, roller, 5, superconducting magnet supporting seat.
Detailed description of the invention
Below in conjunction with accompanying drawing, a most preferred embodiment of the present invention is described further, to help understanding content of the present invention.
As shown in Figure 1 to Figure 2, the present invention includes eight and select post 1, be evenly distributed on same circumference; Be provided with flotation column support 2 in flotation column 1 bottom, below flotation column 1, be provided with superconducting magnet 3, be provided with roller 4 in the bottom of superconducting magnet 3, superconducting magnet supporting seat 5 tops of circumferential are provided with the toroidal cavity matching with roller 4, roller 4 is arranged in groove, superconducting magnet supporting seat 5 tops are also provided with haulage gear, and haulage gear is connected with superconducting magnet 3 outsides. Haulage gear drags superconducting magnet 3 and moves in a circle on superconducting magnet supporting seat 5. In the time that superconducting magnet 3 moves to flotation column 1 below, due to the existence of high-intensity magnetic field, make the fine particle in flotation column 1 be deposited to flotation column 1 bottom, and accumulate in the high-intensity magnetic field district in magnetic field; In the time that superconducting magnet 3 moves to away from flotation column 1, because flotation column 1 is not in field regions, the magnetic-particle in flotation column 1 can be discharged smoothly.
