The present invention relates to a kind of method of gold tailings waste residue multielement recovery, gold tailings waste residue is through vibratory sieve by stone, the extraction such as rubbish is laggard to become owner of feed bin, again by belt conveyor enter ball mill ore grinding after again agitated bucket mine tailing waste residue per ton add 24~26 grams of xanthate, 19~20 grams of flotation oil, enter flotation device after being sufficiently stirred and carry out flotation, the product chosen is iron concentrate, mine tailing is by scanning discharge, enter cyclone through tailings pump, underflow return of serve grinding machine is regrinded, overflow enters after spiral chute the mine tailing of enrichment entering ball mill, flotation device regrinding and reconcentration, content golden in mine tailing is set substantially to reduce, spiral chute mine tailing is extracted into iron ore concentrate through three-level magnetic separation again.The beneficial effects of the invention are as follows：Improved using technique mine tailing mog provided by the invention, the rate of recovery is improved to 84% from original 58%, and grade golden in mine tailing substantially reduces after processing.
Description
Technical field
The present invention relates to a kind of recovery method of mine tailing waste residue, more particularly to a kind of recovery of gold tailings waste residue multielement
Method, belong to mine technology field.
Background technology
Gold ores containing sulfur caused waste residue amount after cyaniding is extracted is very big, especially with people's environmental protection and awareness of saving energy
Improve, the processing of waste residue caused by smeltery just becomes more and more important with recycling, according to current environmental requirement, waste residue
Stacking will build special Tailings Dam to stack, and transport outward and require stricter.
Traditional mine tailing waste residue mineral processing circuit is：For ore deposit after Vibration Screen takes, percutaneous band enters feed bin, then by belt
Transport adds xanthate, flotation oil to ball mill ore grinding, agitated bucket, into flotation device flotation, chooses gold sulfur concentrate, mine tailing is discharged into
Tailings Dam.The technique for not having follow-up mine tailing to extract recovery again, a large amount of wastes of concentrate resource are caused, traditional ore-dressing technique
Shortcoming is：1st, the ore grinding time is short, and mog is thick.2nd, the mine tailing after flotation does not have gold sulfur concentrate recycling equipment, slatterns it
In this part concentrate.
The content of the invention
The present invention recycles deficiency existing for technique for existing gold tailings waste residue, there is provided a kind of gold tailings waste residue
The method of multielement recovery.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of method of gold tailings waste residue multielement recovery, it is characterised in that comprise the following steps：
1) clean：Stone, rubbish sieve are become owner of feed bin by gold tailings waste residue through vibratory sieve except laggard；
2) ball milling：Waste residue in major ingredient storehouse is delivered to ball mill ore grinding；
3) flotation：The product of gained is sufficiently stirred into agitator in step 2), while adds xanthate and flotation thereto
Oil, 24~26 grams of xanthate, 19~20 grams of flotation oil are added in mine tailing per ton, carry out flotation into flotation device afterwards, choose sulphur
Concentrate, mine tailing discharge；
4) separate：The mine tailing of gained is pumped to the separation of centrifugal rotational flow device in step 3), thick below the mesh of gained 100 and weigh
Mine tailing waste residue ball mill is returned to by underflow, gained overflow enters spiral chute gravity treatment, and the mine tailing of gravity treatment acquisition enters magnetic separation
Machine extracts iron ore concentrate, and gained enrichment ore deposit returns to ball mill ore grinding again；
5) washed-out sand：The agitated bucket of mine tailing after magnetic separator extraction takes off after being sufficiently stirred adjustment concentration into sand washer washup
Mud, the mine tailing after desliming enter flotation device；
6) secondary flotation：Using sulfonated petroleum as collecting agent flotation iron containing compoundses, sulfonated petroleum is added in mine tailing per ton
3360g, iron ore concentrate is chosen after being sufficiently stirred；
7) feldspar, quartz are reclaimed：The agitated bucket of mine tailing after step 6) flotation enters length after being sufficiently stirred adjustment concentration
Stone flotation device, using amine as collecting agent, lauryl amine 480g, flotation feldspar are added in mine tailing per ton, quartz is produced in the form of mine tailing
Go out.
Further, the time of ore grinding is 8min in step 2).
Further, the magnetic separator described in step 4) is three-level magnetic separator.
The beneficial effects of the invention are as follows：Improved using technique mine tailing mog provided by the invention, the rate of recovery is from original
58% improve to 84%, grade golden in mine tailing substantially reduces after processing.
Brief description of the drawings
Fig. 1 is the process chart of the present invention；
Embodiment
The principle and feature of the present invention are described below in conjunction with example, the given examples are served only to explain the present invention, and
The non-scope for being used to limit invention.
A kind of method of gold tailings waste residue multielement recovery, comprises the following steps：
1) clean：Stone, rubbish sieve are become owner of feed bin by the gold tailings waste residue in one-level feed bin through vibratory sieve except laggard；
2) ball milling：Waste residue in major ingredient storehouse is delivered to ball mill ore grinding 8min through belt conveyor；
3) flotation：The product of gained is sufficiently stirred into agitator in step 2), while adds xanthate and flotation thereto
Oil, 24~26 grams of xanthate, 19~20 grams of flotation oil are added in mine tailing per ton, carry out flotation into flotation device afterwards, choose sulphur
Concentrate, mine tailing discharge；
4) separate：The mine tailing of gained is pumped to the separation of centrifugal rotational flow device in step 3), thick below the mesh of gained 100 and weigh
Mine tailing waste residue ball mill is returned to by underflow, gained overflow enters spiral chute gravity treatment, and the mine tailing of gravity treatment acquisition enters three-level
Magnetic separator extracts iron ore concentrate, and gained enrichment ore deposit returns to ball mill ore grinding again；
5) washed-out sand：The agitated bucket of mine tailing after magnetic separator extraction takes off after being sufficiently stirred adjustment concentration into sand washer washup
Mud, the mine tailing after desliming enter flotation device；
6) secondary flotation：Using sulfonated petroleum as collecting agent flotation iron containing compoundses, sulfonated petroleum is added in mine tailing per ton
