Description
Technical field
Gold tailings waste residue sand is used the present invention relates to a kind of recoverying and utilizing method of mine tailing waste residue, more particularly to one kind
Method, belong to mine technology field.
Background technology
The waste residue amount that gold ores containing sulfur is produced after being extracted through cyaniding is very big, especially with people's environmental protection and awareness of saving energy
Improve, the processing for the waste residue that smeltery is produced just becomes more and more important with recycling, according to current environmental requirement, waste residue
Stacking will build special Tailings Dam to stack, and outward transport requires stricter.
The processing mode of existing gold tailings waste residue has a disadvantage that：The mine tailing amount in ore dressing plant is very big, and storing up mine tailing needs
A large amount of soils are taken, the mine tailing after natural drying is flown upward with the wind, is polluted, comprehensive utilization should be tried, approach has：
1. many raw ores exploited now of spoil reclaming, grade is less than tailing, and flotation again is extracted, and mine tailing is returning tail
Ore deposit storehouse.
2. underground filling material point hydraulic filling and consolidated fill are made using mine tailing, the latter adds cement or other gelling materials
Material, makes loose mine tailing be condensed into the entirety with some strength.
3. mine tailing brickmaking, cement processed or make some ore dressing plants of the admixture of construction material high silicon tailings be used for making portland
Brick makes aerated concrete products with admixture is made.
4. field and Planting Crops are made with local methods in the Tailings Dam overlying being finished using the multiple field of Tailings Dam and Planting Crops, can kept away
Exempt from mine tailing loss, prevent tailings pollution rivers, increase farming area.
Present building sand significant portion still uses river sand, and river sand directly takes from river, by screen cloth by stone or
Bulky grain sand sieve is removed.
The content of the invention
The present invention recycles the deficiency that technique and building sand production method are present for existing gold tailings waste residue,
A kind of method of use gold tailings waste residue sand is provided.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of method of use gold tailings waste residue sand, it is characterised in that comprise the following steps：
1) removal of impurities：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) it is classified：By step 2) products therefrom is delivered to grader and is classified after ball milling；
4) flotation：By step 3) obtained by product feeding agitator be sufficiently stirred for, while thereto add xanthate with
24~26 grams of xanthate, 19~20 grams of flotation oil are added in flotation oil, mine tailing per ton, flotation device is entered afterwards and carries out flotation, it is selected
Go out iron concentrate, mine tailing discharge；
5) separate：Step 4) in the mine tailing of gained be pumped to the separation of centrifugal rotational flow device, thick below the mesh of gained 100 and weigh
Mine tailing waste residue by underflow return ball mill, gained overflow enter spiral chute gravity treatment, gravity treatment obtain mine tailing enter magnetic separation
Machine extracts iron ore concentrate, and gained enrichment ore deposit returns to ball mill ore grinding again；
6) washed-out sand：The agitated bucket of mine tailing that magnetic separator is extracted after iron ore concentrate sequentially enters one-level after being sufficiently stirred for adjustment concentration
Sand washer, two grades of sand washer washup deslimings, the tailings after cleaning are screened through rotary screen, and the finished product coarse sand on sieve is delivered to stock ground,
The screenings and one-level sand washer of the rotary screen of gained, the overflow of two grades of sand washers are sieved again into three-level sand washer together
Choosing cleaning, the overflow portion of three-level sand washer is precipitated into desliming storehouse, for manufacturing aerated bricks, is cleaned out through three-level sand washer
Fine sand then enter screening machine carry out screening process, be made different model Machine-made Sand.
Further, step 2) in ore grinding time be 8mi n.
Further, step 4) described in magnetic separator be three-level magnetic separator.
Further, step 6) described in one-level sand washer and two grades of sand washers sieve screen apertures be 80 mesh, rotary screen sieve screen apertures
For 40 mesh, the sieve screen apertures of three-level sand washer are 120 mesh.
The beneficial effects of the invention are as follows：
1) the problem of solving Tailings Dam so that gold tailings waste residue need not be emitted into Tailings Dam, after flotation is complete, directly again
Extract, be truly realized and make full use of；
2) element extractions such as the gold in mine tailing, sulphur, iron are come out, then cleaned through sand washer, go the removal of impurity, according to client's need
Classify, the requirement in more clients and market can be reached；
Brief description of the drawings
Fig. 1 is process chart of the invention；
