Abstract
The invention discloses ore dressing equipment, which comprises an ore dressing tank (1), a decanter (2), a stirrer (3) and a slag pulp pump (4), wherein the decanter (2) is positioned on one side in the ore dressing tank (1); the stirrer (3) is arranged at the bottom of the ore dressing tank (2); and the slag pulp pump (4) is arranged outside the ore dressing tank (1) and is positioned on the other side. 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
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 Tailings Dam, 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 concentrator 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 relatively hard problem, 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 with gravity type, adopt the rotary or bellows steel cable type of screw rod; Agitator (2) adopts flat-blade paddle agitator or inclined paddle type agitator; The slag stock pump adopts vertical slag slurry pump or Horizontal slurry pump.
The invention also discloses the method that adopts the said equipment to carry out ore dressing, comprise the steps:
⑴ mine tailing is exploited out afterwards and is formed ore pulp through grinding attachment, and 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 Tailings Dam, has higher economic worth.Can utilize the exploitation mine tailing and reclaim in the process of mine tailing the risk that the elimination Tailings Dam exists.Reduce Tailings Dam environmental disruption and impact.

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 slurry pump.
Describing the first embodiment of beneficiation method of the present invention below in conjunction with Fig. 1, Fig. 2, also is embodiment commonly used.
⑴ mine tailing is exploited out afterwards through grinding attachment, and mog is-200 order 50-80%;
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 the second embodiment.Exploitation mine tailing is out processed without ore grinding, directly puts into ore dressing pond 1 and implements ore-dressing practice.Identical among other steps and the first embodiment.
Fig. 4 is the 3rd embodiment.With the first embodiment difference be, increased after straining the water operation and add water conservancy project skill, because excessive concentration causes line clogging, other are identical with the first embodiment shown in Figure 2 in the time of can avoiding pumping ore pulp.
