Result is sorted it is found that embodiment 2, embodiment 3 by 3 comparative example 2 of table 1- table, embodiment 3 and comparative example 1
And comparative example 1 can play the role of sorting, and can be improved concentrate grade；Sorting Comparative result by embodiment 2 and embodiment 3 can
Know, the magnetic separator with ejector compared with the magnetic separator than not set ejector, sort result concentrate Iron grade and
The rate of recovery is higher, and tailings grade is lower, and the rate of recovery improves 1 percentage point, and tailings grade reduces 5.5 percentage points, has pole
High economic value；It is compared by the separation results of embodiment 3 and comparative example 1 and embodiment 2 and comparative example 1 it is found that the application
By sorting the setting of sieve, it can be improved concentrate grade, reduce tailings grade, improve recovery rate of concentrate；By sorting sieve
And better effect is arranged in the joint of ejector.
In order to probe into the technical principle of the application, the technical solution of the application in order to facilitate understanding by those skilled in the art,
The concentrate and tailing sorted by test case to embodiment 2, embodiment 3 and comparative example 1 is screened, and concentrate and tailing are analyzed
In each grade iron enrichment condition, by table 4, table 6 and table 8 compare it is found that be provided with sorting sieve and ejector column magnetic separator its
Mineral yield in concentrate compared with particulate warp is higher, and fine-graded mineral grade is higher, and in 8 comparative example of table, 1 concentrate screen analysis, carefully
Grade concentrate is less, and then surface, and the magnetic separator of the application can recycle fine fraction magnetic iron ore, overcomes traditional column magnetic separator
Technological deficiency.Just because of the recycling of this part fine-grained minerals, the concentrate Iron grade and the rate of recovery of the application magnetic separator
It is higher, there is high economic value.
In order to further verify the technical principle of the application, pass through the embodiment 2 of table 5, table 7 and table 9, embodiment 3 and right
1 tailing screen analysis result of ratio is it is found that fine-grained minerals are less in the magnetic separator tailing of the application and grade is lower, comparative example
Fine-grained minerals yield in 1 is higher and grade is higher.The magnetic separator of the application overcomes the defect of the prior art, can
Recycle fine fraction and the magnetic mineral of ultra-fine grade in mineral.
Grinding fineness-the 0.074mm of the embodiment of the present application 2, embodiment 3 and comparative example 1 accounts for 83.4%, due to iron ore exploitation
Fast speed, its grinding fineness of existing iron ore needs further increase, it is contemplated that, grinding fineness is thinner, fine fraction and super
The yield of fine-grained minerals is more, and the effect of the application magnetic separator will be apparent from.
Various embodiments of the present invention are described above, above description is exemplary, and non-exclusive, and
It is not limited to disclosed each embodiment.Without departing from the scope and spirit of illustrated each embodiment, for this skill
