Abstract
The invention relates to a multi-element recovery method for waste residues of gold tailings. The method comprises the steps that the waste residues of the gold tailings enter a main bin after stone, garbage and the like are extracted through a vibration screen; then the waste residues enter a ball mill through a belt conveyor for ore grinding; then the waste residues pass through a stirring bucket, 24 g-26 g of xanthate and 19 g-20 g of flotation oil are added to per ton of the waste residues of the gold tailings, the waste residues enter a flotation machine for flotation after being fully stirred, products obtained through concentration are sulfur concentrates, and the tailings are discharged through scavenging; the tailings enter a cyclone through a tailing pump and return to the ball mill for regrinding through underflow; and after overflow enters a spiral chute, the enriched tailings enter the ball mill and the flotation machine for regrinding and re-flotation, the content of gold in the tailings is remarkably reduced, and the tailings of the spiral chute are subjected to three-grade magnetic separation to extract iron concentrates. The method has the beneficial effects that the process is adopted, and therefore the grinded ore fineness of the tailings is improved, the recovery rate is increased to 84% from original 58%, and the grade of the gold in the treated tailings is remarkably reduced.
Description
Technical field
The present invention relates to the recovery method of a kind of mine tailing waste residue, particularly relate to a kind of gold tailings waste residue polynary
The method that element reclaims, belongs to mine technology field.
Background technology
The waste residue amount that gold ores containing sulfur produces after cyaniding is extracted is very big, especially with people's environmental protection and joint
The raising that can realize, the process of the waste residue that smeltery produces just becomes more and more important with recycling, root
According to current environmental requirement, waste residue stacking to be built special Tailings Dam and be stacked, and outward transport requirement is compared
Strictly.
Traditional mine tailing waste residue mineral processing circuit is: ore deposit is after Vibration Screen takes, and percutaneous band enters feed bin,
Again by belt-conveying to ball mill ore grinding, agitated bucket adds xanthate, flotation oil, enters flotation device flotation,
Choosing gold sulfur concentrate, mine tailing enters Tailings Dam.Do not have follow-up mine tailing to extract the technique of recovery again, make
Having become a large amount of wastes of concentrate resource, the shortcoming of tradition ore-dressing technique is: 1, the ore grinding time is short, ore grinding
Fineness is thick.2, the mine tailing after flotation does not has gold sulfur concentrate recycling equipment, slatterns wherein this part essence
Ore deposit.
Summary of the invention
The present invention is directed to existing gold tailings waste residue and recycle the deficiency that technique exists, it is provided that a kind of gold
The method that mine tailing waste residue multielement reclaims.
The technical scheme is that
A kind of method that gold tailings waste residue multielement reclaims, it is characterised in that comprise the steps:
1) remove impurity: stone, rubbish sieve are become owner of feed bin except laggard through vibrosieve by gold tailings waste residue；
2) ball milling: the waste residue in major ingredient storehouse is delivered to ball mill ore grinding；
3) flotation: step 2) in gained product enter agitator be sufficiently stirred for, be added thereto to xanthate simultaneously
And flotation oil, mine tailing per ton adds xanthate 24～26 grams, flotation oil 19～20 grams, enters floating afterwards
Selecting machine to carry out flotation, choose iron concentrate, mine tailing is discharged；
4) separate: step 3) in the tailings pump of gained deliver to centrifugal rotational flow device and separate, below gained 100 mesh
Thick and the mine tailing waste residue of weight returns ball mill by underflow, gained overflow enters spiral chute gravity treatment, weight
The mine tailing that choosing obtains enters magnetic separator and extracts iron ore concentrate, and gained enrichment ore deposit returns ball mill ore grinding again；
5) washed-out sand: the agitated bucket of mine tailing after magnetic separator extraction enters sand washer after being sufficiently stirred for adjusting concentration and washes
Ore deposit desliming, the mine tailing after desliming enters flotation device；
6) secondary flotation: with sulfonated petroleum for collecting agent flotation iron containing compounds, adds sulfonation in mine tailing per ton
Oil 3360g, chooses iron ore concentrate after being sufficiently stirred for；
7) Anhydrite, quartz are reclaimed: through step 6) after the agitated bucket of mine tailing after flotation is sufficiently stirred for adjusting concentration
Enter Anhydrite flotation device, using amine as collecting agent, addition lauryl amine 480g in mine tailing per ton, flotation Anhydrite,
Quartz is with the form output of mine tailing.
Further, step 2) in time of ore grinding be 8min.
Further, step 4) described in magnetic separator be three grades of magnetic separators.
The invention has the beneficial effects as follows: the technique mine tailing mog using the present invention to provide improves, and reclaims
Rate is from 58% original raising to 84%, and in mine tailing, the grade of gold substantially reduces after treatment.
Accompanying drawing explanation
Fig. 1 is the process chart of the present invention；
Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with example, example is served only for explaining this
Invention, is not intended to limit the scope of invention.
A kind of method that gold tailings waste residue multielement reclaims, comprises the steps:
1) remove impurity: stone, rubbish sieve are become owner of except laggard by the gold tailings waste residue in one-level feed bin through vibrosieve
Feed bin；
2) ball milling: the waste residue in major ingredient storehouse is delivered to ball mill ore grinding 8min through belt conveyor；
3) flotation: step 2) in gained product enter agitator be sufficiently stirred for, be added thereto to xanthate simultaneously
And flotation oil, mine tailing per ton adds xanthate 24～26 grams, flotation oil 19～20 grams, enters floating afterwards
Selecting machine to carry out flotation, choose iron concentrate, mine tailing is discharged；
4) separate: step 3) in the tailings pump of gained deliver to centrifugal rotational flow device and separate, below gained 100 mesh
Thick and the mine tailing waste residue of weight returns ball mill by underflow, gained overflow enters spiral chute gravity treatment, weight
The mine tailing that choosing obtains enters three grades of magnetic separators and extracts iron ore concentrate, and gained enrichment ore deposit returns ball mill and again grinds
