4, the true tailings that after the magnetic separation of second SLon magnetic separator, obtains is the finished product zircon sand, the titaniferous grade TiO of zircon sand
2≤15%.
The mixed type beach placer characteristic that the spiral chute gravity treatment obtains: fine size-0.074mm is about 80%, and ilmenite distributive law height contains TiO
2≧ 97%; Be rich in monazite and zircon sand, the difference in specific gravity of three kinds of mineral is little, again because the magnetic of the monazite of the ilmenite magnetic of microfine and larger particles is close; Common intensity magnetic separator is difficult to they are separated, thereby traditional method for separating can only utilize electric separation to separate.
The present invention breaks through traditional process; Obtain to roughly select comprehensive concentrate with the spiral chute gravity treatment earlier; Adopt the selected replacement electric separation of segmentation of SLon magnetic separator again; Adopt the selected segmentation of magnetic separation to sort, simultaneously in the magnetic separation process the auxiliary big pulsating fluid field of force and medium-width magnetizing mediums carry out twice selected to sort out the high-quality ilmenite concentrate, titaniferous grade TiO
2≧ 47%; Again the mine tailing of selected ilmenite being adopted twice of high field intensity and big width magnetizing mediums, selected true tailings is a zircon sand to sort out monazite, thereby has reached the purpose of effectively isolating ilmenite concentrate, monazite and zircon sand.

-6/ g), weak (the specific susceptibility 18cm of the magnetic of monazite
-6/ g); But the magnetic of the ilmenite of micro-size fraction is close with the magnetic of big grade monazite, if adopt the stronger clean ilmenite of the disposable choosing of magnetic force of seizure power, will cause and carry a large amount of monazites in the ilmenite secretly; If instead adopting the more weak selected bulky grain ilmenite of magnetic force of seizure power chooses earlier; Still have the ilmenite of a large amount of micro-size fractions not choose, influence the ilmenite rate of recovery, on sorting process so the present invention adopts segmentation to sort.
2, the pulsating fluid field of force: the branch constituency of SLon magnetic separator also has the pulsating fluid field of force except that field of magnetic forece and gravitational field are arranged, and pulsating flow muscle power can be adjustable at random to the sorting of different minerals.The less pulsating fluid field of force is adopted in the sorting of traditional fine fraction beach placer, and the present invention then adopts the big pulsating fluid field of force, has so not only obtained high-quality ilmenite concentrate but also has reduced carrying secretly of bulky grain monazite.
3, magnetizing mediums: magnetizing mediums is the trap setting that magnetic separator sorts magnetic mineral.The sorting of traditional fine fraction beach placer is that employing medium width is less, specific area big, fine fraction is caught the strong little width magnetizing mediums of power; The present invention adopts then that the medium width is big, specific area suitably, fine fraction caught the big preferably width magnetizing mediums of power come selected ilmenite; Decapacitation obtains outside the high-quality ilmenite like this, and also the sorting for monazite and zircon lays the first stone.
