The invention also discloses a method for ore dressing by adopting the ore dressing equipment. The invention can effectively recover iron metal existing in a form of Fe2O3, recycles tailings stacked in a tailing pond, has higher economic value, can eliminate the risk of the tailing pond in the process of exploiting and recovering the tailings, and reduces the damage and influence of the tailing pond to/on the environment.

Description

A kind of preparation equipment and beneficiation method
Technical field
The invention belongs to the iron ore beneficiation field, the spoil reclaming that relates to the iron ore mine storehouse utilizes the field, is specifically related to a kind of preparation equipment and beneficiation method.
Background technology
The mine tailing of present stage iron ore mine eliminating mainly is deposited in the mine tailing storehouse, also has a certain proportion of ferrous metal in the mine tailing.Ferrous metal in the mine tailing is mainly with Fe 2O 3Form exist because Fe 2O 3Do not have magnetic, and present iron ore dressing plant is in the majority in the magnetic separation mode, to Fe 2O 3The ferrous metal that mode exists reclaims relatively difficulty.
Summary of the invention
In order to solve with Fe 2O 3The ferrous metal that mode exists reclaims the relatively problem of difficulty, the invention provides a kind of preparation equipment, it is characterized in that: comprise the ore dressing pond, strain hydrophone, agitator and slag stock pump, straining hydrophone is arranged on and is positioned at a wherein side in the ore dressing pond, agitator is arranged on the bottom in ore dressing pond, and the slag stock pump is arranged on outside the ore dressing pond, is positioned at opposite side.
Further, reinforced concrete structure is adopted in the ore dressing pond; Strain hydrophone (2) and strain hydrophone, adopt the rotary or bellows steel cable type of screw rod with gravity type; Agitator (2) adopts flat-blade paddle agitator or inclined paddle type agitator; The slag stock pump adopts vertical slag slurry pump or horizontal slag stock pump.
The invention also discloses the method that adopts the said equipment to carry out ore dressing, comprise the steps:
⑴ form ore pulp through grinding attachment after mine tailing is exploited out, mog is-200 order 50-80%;
⑵ ore pulp is put the ore dressing pond into, accumulates 80% of ore dressing pond (1) total capacity;
⑶ start agitator, closes agitator after stirring;
⑷ ore pulp precipitates in the ore dressing pond;
⑸ hydrophone is strained in startup, and the ore pulp that is deposited in top, ore dressing pond is drained;
⑹ start agitator, even remaining flowsheet of slurry agitation;
⑺ start the slag stock pump, and the ore pulp in the ore dressing pond is pumped, and finishes ore-dressing practice.
On the other hand, mine tailing also can directly be put the ore dressing pond into without grinding attachment, carries out ore dressing.
Further, after ore pulp is drained, add water.
Further, the time 20min-8h that in the ore dressing pond, precipitates of ore pulp.
The present invention can effectively reclaim with Fe 2O 3The ferrous metal that mode exists is recycled the mine tailing that is deposited in the mine tailing storehouse, has the higher economic value of ratio.Can utilize the exploitation mine tailing and reclaim in the process of mine tailing, eliminate the mine tailing stock risk.Reduce the mine tailing storehouse to environment damage and influence.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, preparation equipment of the present invention comprises ore dressing pond 1, strains hydrophone 2, agitator 3 and slag stock pump 4.Reinforced concrete structure is adopted in ore dressing pond 1, strains hydrophone 2 and adopts gravity type to strain hydrophone, strains hydrophone and can select the rotary and bellows steel cable type of screw rod.Straining hydrophone 2 is arranged on and is positioned at a wherein side in the ore dressing pond 1.Agitator 2 is arranged on the bottom in ore dressing pond 2, can adopt flat-blade paddle agitator and inclined paddle type agitator.Slag stock pump 4 is arranged on outside the ore dressing pond, is positioned at opposite side.Slag stock pump 4 adopts vertical slag slurry pump or horizontal slag stock pump.
Describing first embodiment of beneficiation method of the present invention below in conjunction with Fig. 1, Fig. 2, also is embodiment commonly used.
⑴ through grinding attachment, mog was-200 order 50-80% after mine tailing was exploited out;
⑵ ore pulp is put ore dressing pond 1 into, accumulates 80% of ore dressing pond total capacity;
⑶ start agitator 3, closes agitator 3 after stirring;
⑷ ore pulp precipitates 20min-8h in the ore dressing pond;
⑸ hydrophone 2 is strained in startup, and the ore pulp that is deposited in top, ore dressing pond is drained;
⑹ start agitator 3, even remaining flowsheet of slurry agitation;
⑺ start slag stock pump 4, and the ore pulp in the ore dressing pond is pumped, and finishes ore-dressing practice.
Fig. 3 is second embodiment.The mine tailing that exploitation is come out is handled without ore grinding, directly puts into ore dressing pond 1 and implements ore-dressing practice.Identical among other steps and first embodiment.
Fig. 4 is the 3rd embodiment.With the first embodiment difference be, after straining the water operation, increased and add water conservancy project skill that because excessive concentration causes line clogging, other are identical with first embodiment shown in Figure 2 in the time of can avoiding pumping ore pulp.
