Description

The general preparation equipment of one heavy metal species

Technical field

The utility model belongs to ore separators technical field, and in particular to the general preparation equipment of a heavy metal species.

Background technology

Reselection technique mainly has these three modes of spiral separation, jigging, shaking table at this stage.However, spiral point is used alone Disembark or jigging equipment, although having the advantages that treating capacity is big, exist mine rate is low, precision is low, it is high to run tail, and to 200 mesh Above material can not be handled；And shaking table equipment is used alone, although certain Product Precision can be improved, obtain a part Mineral more than 200 mesh；But day output is small, and race tail cannot also solve.

For example, application No. is 201410314014.0 Chinese invention patent application, a kind of pressure dissolved air floatation method is disclosed The technique and device for removing heavy metal ions in sewage belong to environmental project and administer field.The technique first will first lead to waste water Entering calcium hydroxide makes it neutralize the acid ion in waste water, then is passed through the sediment hydrophobization that enuatrol makes to be formed, and then makes Grain flocculation；Microbubble is generated using pressure air-dissolving method, the saturated dissolved gas water generated after pressurization is passed dirty by being discharged into flocculation Flotation is carried out in water；Finally the dross floatingly selected is collected and handled.

In another example application No. is 200410103975.3 Chinese invention patent application, a kind of combined type rock gold is disclosed Tailings recovery device, it includes：Submersible deep layer rushes device for picking, ore pulp splitter, pulp distributer and ore pulp and carefully selects, rushes Equipment is washed, by reselection modes, three high-recovery, high throughput, optimization enrichment aspects has been taken into account, has achieved good effect Fruit.

Above equipment is combined and is used, although being taken on a new look, the problem of running tail, always cannot solve at all, Especially to mineral materials more than 200 mesh, even more it is difficult to handle.The race tail of entire gravity treatment mining industry, main is exactly more than 200 mesh Material in, the general tail that runs is traced it to its cause 0.5% or more：

1. mud and material mixing washing simultaneously.Thus it can also carry away part secretly while mud is washed away Tiny mineral material.

2. the granular size of material is not equal, thickness regardless of, mix choosing together.Because the weight of the big sandstone of particle is much big In the weight of tiny mineral, this is easy for causing to run tail.20 purposes are only spaced if separation with mesh net the producer having Volume separates, and since body integral difference is big, weight difference is just big, and therefore, effect is also with regard to unobvious.It is washed away during washing big While the sandstone of particle, also it is easy for washing away short grained mineral.

3. during washing, the material for supplying shaking table is more or less, very unstable, this just makes material on shaking table Downward movement Orbit revolutionary is continuous, can not strictly control, and may result in this way in the concentrate that institute's washing comes out doped with chats；In Doped with concentrate and tailings in mine；Doped with chats in tailing, here it is cause mine rate is low, low precision, runs the high reason of tail.

4. all producers all purify obtained mineral products that work is not further, the reason is that obtained mineral products Large or fine granule mixes, it is difficult to be purified to it, this mineral products for resulting in grade low is when selling in addition to increasing transport pressure and fortune Outside defeated cost, also have a greatly reduced quality in price.

5. using shaking table coal washing technique at this stage, mineral facies more than 200 mesh of precision and extraction of obtained mineral products Than being higher in other gravitational separation equipment；Using the producer of combination coal washing technique, shaking table is all put into last procedure, but shake The bed washing ability of itself has mud in material with regard to extremely limited containing miscellaneous, and material particles size thickness and regardless of, In this case, it should expect high-precision mineral products, want to improve treating capacity again, it is difficult to realize.

6. most producers for using reselection technique now, the processing to tailing, silt is all to build tailing dam, disadvantage End be to invest it is big, take up an area it is more, but also buried chance heavy rain, may cause damages when Freshets roar down from the mountains great dam break hidden danger.
