Accompanying drawing explanation
Fig. 1 is the mineral processing circuit figure of lead zinc-silver of the present invention.
Detailed description of the invention
The claim of the present invention is described in further detail by the mode below in conjunction with specific embodiment, but not structure
Becoming any limitation of the invention, the amendment of anyone limited number of time made within the scope of the invention as claimed, still at this
Within bright right.
In view of this, the invention provides the ore-dressing technique of a kind of Pb-Zn-Ag ore, raw ore ore grinding in grinding operation is thin
Degree accounts for 50%～60% for-200 mesh；Raw ore after ball milling first carries out selecting the lead in Lead exposed to roughly select, and described lead includes before roughly selecting
Add the step of diesel oil；Selecting the raw ore after Lead exposed to carry out selecting the zinc of zinc operation to roughly select, described zinc includes before roughly selecting adding bavin again
The step of oil.
Above-mentioned, diesel oil is non-polar hydrocarbon oil collecting agent, is the one of nonionic collecting agent.Diesel oil is adsorbed in galena
Surface, has the flotation of preferable hydrophobicity, beneficially galena, it is to be understood that diesel oil can be light diesel fuel, it is also possible to by
Kerosene or emulsified kerosene replace, and all can obtain preferable galena flotation effect, and lead recovery improves.
It is to be appreciated that in Pb-Zn-Ag ore floatation process, when using controling differential flotation process for copper, select sphalerite in Lead exposed past
Toward receiving strong suppression, if it not being activated in selecting zinc operation, it is difficult to the higher zinc recovery taken.Sphalerite activates
Agent has copper, lead, silver, cadmium ion and novel activated dose, but using copper ion as activator best results, medicament price is minimum, lives
Change effect the strongest.
But, when only adding mentioned component, zinc there will be the most serious race groove phenomenon during roughly selecting, through specialty
The analysis of technical staff, has found that the impact of the factors such as pulp density, pharmaceutical quantities and granularity, causes floatation process process drastically
Change, thus it is abnormal to cause froth bed thickness and foam to scrape output.It can show two kinds of extreme phenomenons: one is ore deposit liquid
Face falls, and can not scrape foam；Another kind be a large amount of ore pulp and foam excessive, this phenomenon be referred to as " race groove ".
After adding diesel oil, zinc rougher process inhibits serious race groove phenomenon, and diesel oil is for the collecting energy of sphalerite
Power is strong, and sphalerite floats in a large number, and zinc recovery is brought up to more than 80% by 0 before improving～20%.Annual lead concentrate after improvement
Leaded 68.51%, mutually containing zinc 2.31%, lead recovery 96.90%, lead concentrate argentiferous 1000g/t, silver raising recovery rate 90%, zinc essence
Ore deposit contain zinc 47.92%, the most leaded 1.22%, zinc recovery 77.63% improve after lead recovery 96.90%～99.00%, silver return
Yield 90.00%～92.00%.
Before improvement, former year production target: lead concentrate leaded 68%, mutually containing zinc 2.4%, lead recovery 93%, lead concentrate contains
Silver 8500g/t, silver raising recovery rate 79%, zinc concentrate contain zinc 47%, the most leaded 1.8%, zinc recovery 58%.
Contrast before and after improvement: lead recovery improves 3.9%, and silver raising recovery rate improves 11%, and zinc recovery improves
19.37%, flotation effect highlights.
It is to be appreciated that the raw ore leaded 8.60% that the present invention uses, containing zinc 2.98%, silver 140g/t, sulfur content is high
Reach more than 25%, for high-sulfur Pb-Zn-Ag ore.
Confirming through long-term practice, this kind of beneficiation method is applicable to lead zinc-silver high-sulfur ore deposit, and the difficult ore dressing that degree of oxidation is higher
In, it is respectively provided with preferable flotation effect, significantly improves high-sulfur ore deposit, the response rate of difficult ore dressing, reduce Financial cost.
Further, the step that water processes also is included: in Pb-Zn-Ag ore beneficiation wastewater, put into six by per ton 1～10g/t
Polymeric sodium metaphosphate..
Above-mentioned, existing water treatment procedure need the aluminum sulfate of interpolation, polyacrylamide, activated carbon, sodium carbonate, sulphuric acid sub-
Ferrum.Water treatment efficiency is poor, and water pollution is difficult to be improved, and polyacrylamide is Organic substance, poorly water-soluble, viscosity
Greatly, easily blocking the pore of ceramic wafer, dust technology is difficult to react, and, activated carbon constituents the most easily blocks the hair of ceramic wafer
Pore, and dust technology is difficult to react, in the short time, the ceramic wafer after blocking i.e. loses water filtering function.Existing water-treated
Journey, is not only difficult to avoid that water pollution, and relatively costly
And sodium hexameta phosphate improves the ability of water quality by force as water softener, put into 5g/t by Pb-Zn-Ag ore beneficiation wastewater per ton
Sodium hexameta phosphate, the 180g/t aluminum sulfate added than former common process, the improvement effect of 5g/t polyacrylamide is more preferable.And
Cost of water treatment is substantially reduced.And, sodium hexameta phosphate is ionic compound, in ore pulp, exists with ionic condition, does not affects
Lead concentrate, zinc concentrate, tailing filtration, the length in service life of ceramic wafer, low cost, simultaneously good filtration effect, product moisture is low.
It is understood that owing to sodium hexameta phosphate addition is less, remain the activity of residual pharmacy in floatation process,
Residual pharmacy in waste water can continue to for flotation, and floating agent cost significantly reduces.
Even if at Tibet Autonomous Region's temperature below 10 degree, floating agent dosage is the least, and floatation indicators is the most fine.
And before improving, temperature is the lowest, and dosing is the biggest, floatation indicators is deteriorated.
After the method that water processes is improved, waste water has accomplished zero-emission.
Further, further comprising the steps of: lead is roughly selected and selected lead rougher tailings and lead rough concentrate respectively；Wherein, lead is thick
Selecting mine tailing to scan, lead rough concentrate carries out selected.
Above-mentioned, scan the response rate that can improve galena, the selected concentrate grade that improves, reduce the mineral without economic worth
And stone-like pulse, improve concentrate grade and further increase its market value.
Further, the lead cleaner tailings every time scanning out carries out the dressing process of more than twice again, scans out
Lead cleaner tailings carry out again more than twice scan technique.
Further, in lead rougher process, also by raw ore per ton input Calx 1～3kg/t, zinc sulfate 300～500g/t,
Butyl ammonium aerofloat 4～6g/t, sulfur nitrogen No. 9 50～150g/t, diesel oil 100～200g/t.
Above-mentioned, Calx can be lime cream or quick lime, is typically formed by ball mill grinding.On the one hand Calx be in ore dressing
The pH adjusting agent of floating agent, and be also pyrite inhibitor.During lead is roughly selected, add Calx, suppress lead zinc-silver
Pyritous floating in ore deposit, improves collecting effect.And owing to Calx is relatively inexpensive, it is effectively controlled the choosing of Pb-Zn-Ag ore
The cost of miner's skill.
Zinc sulfate and Calx can produce HZnO in ore pulp2-and ZnO2 2-Hydrophilic colloid adsorb on sphalerite surface,
Thus reduce the floatability of sphalerite to reach inhibition, and OH-can show to generate Fe (OH) at pyrite3Hydrophilic gel
Body is to suppress pyrite, it is also possible to and " unavoidable ion " Cu in ore pulp2+Generate Cu (OH)2Precipitation, thus avoid it to activate
Sphalerite and pyrite.So-called " unavoidable ion " is that mineral receive oxidation and hydration in water, causes inside mineral lattice
Bond energy weakens, destroys, so that some ion-solubility of surface get off.Ion intrinsic in these ions and water is referred to as " unavoidable
Ion ".
Butyl ammonium aerofloat is that the excellent collecting agent of nonferrous metallic ores is held concurrently foaming agent.To copper, lead, silver and the ore deposit of zinc activated
And difficulty selects polymetallic ore to have special separating effect.Its collecting performance to pyrite and magnetic iron ore in alkalescence ore pulp
More weak, and stronger to the collecting ability of galena.
Sulfur nitrogen 9 is lead minerals selective copper collector, and technique is widely used, and sorting result is notable.Use diethyldithiocarbamate conduct
Lead minerals collecting agent diffeential floatation lead minerals, decreases the consumption of zinc inhibitor, and lead recovery improves, and index is preferable.
Further, in zinc rougher process, also by raw ore per ton input Calx 1～3kg/t, copper sulfate 100～200g/t,
Butyl xanthate 20～30g/t, diesel oil 100～200g/t.
Above-mentioned, it is to be understood that in Pb-Zn-Ag ore floatation process, when using controling differential flotation process for copper, select in Lead exposed and dodge
Zinc ore has suffered from strong suppression, if not activating it in selecting zinc operation, it is difficult to the higher zinc recovery taken.Dodge zinc
Ore deposit activator has copper, lead, silver, cadmium ion and novel activated dose, but using copper ion as activator best results, medicament price
Minimum, activation effect is the strongest.Therefore the present invention has selected copper sulfate.
Butyl xanthate is the floating agent that a kind of collecting ability is stronger, and it is widely used in the mixing of various nonferrous metals ore and floats
Choose.These product are particularly suitable for sphalerite, can the sphalerite of effectively collecting copper sulphate for activation.
It is understood that refering to Fig. 1, the flotation agent situation added in each flow process is as shown in Figure 1.Lead is roughly selected II and is swept to lead
Adding floating agent sulfur nitrogen 9 by 40g/t per ton when selecting I, lead is scanned when I scans II to lead and is added flotation medicine by 30g/t per ton
Agent sulfur nitrogen 9, lead roughly selects II and adds floating agent zinc sulfate to the selected I of lead by 150g/t per ton, and the selected I of lead to the selected II of lead is by every
Ton 0.2kg/t add Calx, zinc roughly select zinc scan I by 90g/t per ton add butyl xanthate, by 25g/t per ton add zinc sulfate,
Zinc scan I to zinc scan II by 36g/t per ton add butyl xanthate, by 24g/t per ton add zinc sulfate.
Further, the step that water processes also is included: in Pb-Zn-Ag ore beneficiation wastewater, put into six by per ton 3～8g/t inclined
Sodium phosphate.
Further, lead rougher tailings addition sulfur nitrogen 9 is scanned；Lead rough concentrate adds Calx and carries out selected.
Above-mentioned, in floatation process, the foam with Ore particulate floated to be scraped by we, with big on foam
Amount medicament, along with scraping of foam, the medicament in ore pulp below reduces relatively, so needing to add later.It is understood that
, medicament can not be added in above excess, medicament excess, overdose of medicine agent can be useless to other or without economic worth
Mineral and stone-like pulse collecting get up, cause concentrate grade the lowest, affect selling price.Further, due to the flotation speed of some ore particle
Degree is relatively slow, needs to add some medicaments to reclaim this part ore particle below.
Present invention also offers the floating agent of a kind of Pb-Zn-Ag ore, including Calx, zinc sulfate, butyl ammonium aerofloat, sulfur nitrogen 9
