The method that the difference of object floatability is sorted.Flotation is also widely used in the technique of alum recovery.In the flotation of alum recovery
The suspension of generally use ferrosilicon fine particle is as flotation medium in technique, and after floatation process, it will usually use magnetic
Machine is selected to recycle flotation medium, the specific steps are：1, the aluminium material floatingly selected is placed on sculping screen, using water to aluminium material into
Row is sprayed, and the medium that surface is adhered to is made to be flush with water totally, and spray is formed by later in spray tail washings to be situated between containing a large amount of
Matter；2, spray tail washings enters the progress medium separation of subsequent magnetic separator, is returned after isolating the higher dielectric suspensions of concentration
It receives and recycles, remaining magnetic tail mineral water waste treatment.However, since the efficiency of current magnetic separator is unable to reach higher level, lead
The medium being recovered to is caused only to account for total using 60% or so of medium, remaining part is given up among being then present in magnetic tail mineral water
It abandons, this makes the cost in floatation process using medium be up to more than half of totle drilling cost.Therefore, if can effectively return medium
It receives, then can greatly reduce cost, while also saving resource.

Using above-mentioned technical proposal, existing one-part form recovery process is changed to by flotation medium recovery system of the invention
Two-part recovery process tentatively cleans aluminium material by first segment sculping screen in first segment recovery process, then by aluminium material
It moves in second segment sculping screen and is cleaned comprehensively；And the spray tail washings generated in second segment sculping screen carries out magnetic separation recovery Jie
Remaining magnetic tail mineral water is discharged without exhaust gas after matter, but is delivered to the re-using of first segment spray equipment, to make the
Medium in the magnetic tail mineral water generated in two stage magnetic separators will not be wasted, and only make the magnetic generated in the first stage magnetic separator
Medium in tailing water is not recovered, therefore can improve the rate of recovery of medium to 90% or more, greatly from existing 60%
Ground improves the rate of recovery of medium, has saved cost, and resource is made adequately to be recycled.
