Utilize taper seat 6 to carry out the enrichment of mine tailing, taper seat is for 45-48% (preferred 46.5%), and the cone top is provided with automatic rotation mine distributor 5; Carry out 360 ° of branch ore deposits; When the mine tailing deposit thickness reaches about 0.3 meter (0.25-0.35m), accomplish one time enrichment process, lean on the mine tailing of thick about 0.1 (0.06-0.15) rice in cone surface to add an amount of sulfuric acid 8kg and butyl sodium xanthate 3kg; Carry out the taper seat enrichment second time, cone surface ground floor is the taper seat concentrate; The second layer is a chats, gets into the chats shaking table and reclaims; The 3rd layer is mine tailing, gets into mine tailing;
Utilize floating trough 7 flotation concentrates, the middle-end of floating trough 7 is the gradient of 35-38% (preferred 36.5%), and the rear end of groove is the gradient of 1-4% (preferred 2%); Insert in the floating trough 7 from the concentrate of taper seat 6; Add an amount of sulfuric acid 8kg and butyl sodium xanthate 1.5kg, after stirring, spray with clear water after 15～20 minutes; Impurity is rinsed out, promptly select tin concentrate 8.
1. mine tailing classification:
The mine tailing classification can be adopted cyclone classification and two kinds of methods of sieve classification.Cyclone classification is easier, is convenient to control flow, but needs bigger drop.
The sieve classification construction is fairly simple, and relative relief is little, but needs the periodic replacement compass screen surface, increases the cost of sieve.
According to the mine tailing flow, can use one or more cyclones or sieve to carry out the mine tailing classification.
Cyclone can be used brick mix structure, and top is cylinder, and the lower end is a funnel type; Mine tailing gets into cyclone near the top along the tangential direction of cyclone cyclone; Make mine tailing in cyclone, form eddy flow, various mineral form different sinking speed according to self granularity and proportion size; The thin mine tailing in top gets into shop cloth chute, and the bottom gets into next cyclone or gets into table concentration than thick and the bigger mine tailing of proportion.
2. shop cloth chute is received the ore deposit:
Shop cloth chute is used cement plaster by the concrete shop fixtures, and surfacing is smooth, and the gradient is consistent, in chute, lays woollen blanket cloth.The upper end of mine tailing cloth chute from the shop flows into chute.More even for the mine tailing flow velocity and the thickness that make the chute surface, the upper end of chute should be provided with Buffer Pool, and the mine tailing in the Buffer Pool flows into chute through a series of (for example 6) aperture.Mine tailing is through shop cloth chute, and the mineral that proportion is bigger can precipitate and be adsorbed on the woollen blanket cloth, and the mine tailing of upper end is closed in (for example 20 minutes) at set intervals, and with woollen blanket of high pressure water washing, water under high pressure hydraulic pressure should be not less than 2kg/cm
2, so that efficient is high and clean towards the ore deposit, the mine tailing that develops is concentrated and is got into sedimentation basin.
3. taper seat enrichment mine tailing:
The outer likeness in form yurt of taper seat, taper seat is the taper seat that cement is constructed, and cone gradient l for example is 46.5%, and the gradient is consistent up and down, and surfacing is smooth, and the cone top is provided with automatic rotation mine distributor.The mine tailing that shop cloth chute is collected, through flowing to the mine distributor that the taper seat top is provided with certainly, mine distributor leans on the impulsive force rotation of mine tailing flow velocity; Carry out 360 ° of branch ore deposits, make mine tailing equably from the taper seat top along under the cone surface current, and around the cone base deposition; When the mine tailing deposit thickness reaches 0.3 meter left and right sides, should stop to the ore deposit, promptly accomplished enrichment process one time; Lean on cone surface one deck, thick about 0.1 meter, the grade of tin can reach about 2%; The mine tailing of this part enrichment is added an amount of sulfuric acid 8kg and butyl sodium xanthate 3kg, select dosage according to the sulfur content of mine tailing.Carry out the enrichment of the secondary circle conical surface according to above-mentioned same method, cone surface ground floor is the taper seat concentrate, and the grade of tin can reach about 5%, dry measure 400～500kg.The second layer on taper seat cone surface is a chats, and chats gets into the chats shaking table and reclaims, and outward the 3rd layer of taper seat cone surface be mine tailing, mine tailing entering mine tailing ditch.
4. floating trough concentrate:
Floating trough is the groove that is used for flotation taper seat concentrate, and long 3.70 meters, 1.40 meters of the middle-ends of groove are made 36.5% the gradient, and 2 meters of the rear ends of groove are long, make 2% the gradient.Every groove can be handled concentrate 400～500kg that taper seat is produced, and the taper seat concentrate is inserted in the groove, adds after an amount of sulfuric acid 8kg and butyl sodium xanthate 1.5kg stir; Treat that it carries out the chemical reaction of 15～20 fens clock times; With the clear water spray, at leisure impurity is rinsed out then, promptly select the tin concentrate; The concentrate grade about 40% of tin, every groove reclaim about tin metal amount 30kg.
Embodiment
In one embodiment, 600 tons in day processing raw ore, 558.3 tons of mine tailing amounts, tailings concentration 12% is selected 2 cyclones for use, 48 shop cloth chutes, 24 4m
3Sedimentation basin, 8 taper seats, 9 shaking tables, 4 flotation cells.In other embodiment, scale also can continue to enlarge, with many recovery tin concentrate.
If tailings concentration is big, in the cloth chute of shop, just can not evenly flow, be prone to form mine tailing and pile up.At this moment, can add water, reduce tailings concentration.In one embodiment, tailings concentration is at 10-15%, and preferred 12%.
During the mine tailing classification, control the granularity of mine tailing.Get into the mine tailing grade of shop cloth chute and the test result of tin grade behind the cyclone classification and see table one.
Table one
| Grade (mm) | Total amount (g) | Productive rate (%) | Tin grade (%) | Tin metal distributive law (%) |
| ±0.175 | ?131 | 11.91 | 0.298 | 13.40 |

| -0.019 | ?398 | 36.18 | 0.330 | 45.07 |
| Add up to | ?1100 | 99.99 | 100.00 |
The test result of floating trough concentrate grade and tin grade is seen table two.
Table two
| Grade (mm) | Total amount (g) | Productive rate (%) | Tin grade (%) | Tin metal distributive law (%) |
| +0.175 | ?310 | 17.96 | 45.51 | 18.53 |

| -0.019 | ?211 | 12.22 | 43.81 | 12.14 |
| Add up to | ?1726 | 99.99 | 99.99 |
Table two shows, for the fine tin mineral of-0.019mm, the rate of recovery is still lower.The grade 0.33% of tin in the mine tailing of selected shop cloth chute, the distributive law of tin accounts for 45.07%, and in the tin concentrate that reclaims-the tin mineral productive rate of 0.019mm only occupies 12.14%.In a further embodiment, can carry out a taper seat again to the floating trough mine tailing and reclaim, recovering effect can be better.
Select the overflow water of factory's byproduct sulphur concentrate, the smart powder of iron can not get in the mine tailing of recycling, otherwise can increase the content of beary metal in the mine tailing, influence the rate of recovery of tin in the mine tailing.
Tailing reclaims the recycling that technological process is equally applicable to gravity tailings such as tungsten ore mountain.
