Description
Technical field
The present invention relates to a kind of magnetic separating device, particularly a kind of superconducting magnetic separation device that can be used for ore dressing.
Background technology
Since the magnetic separating device that nineteen thirty-seven Fu Langzi invention ore dressing is used, magnetic separation ore-sorting technology has obtained significant development.Particularly superconducting magnetic separation device drops into the mine and already uses over more than 30 year, and superconductor technology and magnetic separation technique constantly develop, and interpenetrate, and merges each other and promotes, makes the magnetic separation technique range of application more and more wider.The fast development of magnetic separation ore-sorting technology is based on several kinds of reasons:
1, magnetic separation ore-sorting technology is a kind of physical separation method, compares with chemical method, and magnetic separation technique technology is simple, environmentally safe, compliance with environmental protection requirements.
2, from world wide, the rich ore that iron-holder is high is fewer and feweri, and a large amount of lean ores and mine tailing wait for and recycling that magnetic separates and can play a great role.
3, along with the development of superconductor technology, superconductor technology has been moved towards application and has been combined with magnetic separation technique from the laboratory, and superconduction magnetic separation magnet uses superconducting line, and resistance is zero, and operate power is low, greatly energy savings.
Magnetic-particle receives the effect of magnetic force in the space of changes of magnetic field, the big I of magnetic force is expressed as:
F
m＝KVH
dH/
dx
Wherein: the susceptibility of K-particle
The volume of V-particle
The H-magnetic field intensity
The dH/dx-magnetic field gradient
In same magnetic field, the material of different magnetic is stressed different, depends on the susceptibility of particle.The distance that the different material of magnetic is put in magnetic field gradient one lateral deviation is different, thereby reaches the purpose of separation.
In the filtering type magnetic separating device, the captive primary condition of magnetic-particle is magnetic force F
mGreater than gravity F
gWith fluid viscosity resistance F
DYet, can find out by following formula, for specific magnetic separating device since its magnetic field intensity fix, so the volume of the particle that can separate through magnetic separation-be that the sorting scope also is certain.Existing often lead the high gradient magnetic separator background magnetic field and be bordering on 1T, iron particle that can sorting is basically more than 50 μ m.
China's high-grad iron ore deposit resource is few, and hematite and bloodstone resource are many, account for total resources more than 60%.And the fine grained ore below the 30 μ m utilizes the existing magnetic separator of often leading not separate, and its consequence is that a large amount of resources is not used on the one hand, causes very big environmental problem on the other hand.
In addition, China's aluminium oxide industry yearly productive capacity is through nearly 3,000 ten thousand tons.Usually contain more iron in the bauxitic feed materials, the residue that the extraction aluminium oxide stays later on is called as red mud (taking on a red color owing to containing iron oxide, so claim red mud).Iron content reaches 20-30% by weight percentage usually approximately in the red mud, sometimes up to about 50%.Because the needs of technology, it is very thin that bauxite generally will grind, and particle over half is below 20 μ m.Therefore utilize conventional magnetic separator also to be difficult to separate, cause the iron ore deposit in the red mud to be wasted because of can not rationally utilizing.
And superconducting magnet has higher magnetic field intensity, generally can reach 3-5T, but the iron grain diameter of sorting is 10 μ m left and right sides susceptibilitys 5 * 10 in theory
