Abstract
The present invention relates to a kind of method of eliminating the flotation concentrate mineralized froth.This method is to adopt the defoamer of surfactant, eliminates the physical chemistry processing method of mineralized froth deposit seed metalliferous mineral.The raw material of this defoamer is from the petroleum product low price, and human body and environment are not all had influence.By test of many times and production practices, froth breaking is stable, the granular metal mineral can precipitate rapidly.Particularly can save thickener, jet pump, filtering machine in traditional dehydration workshop section, the dewatering process system is simplified greatly.
Description
The present invention relates to a kind of method of eliminating mineralized froth, this method is to adopt defoamer to eliminate the physical chemistry processing method of mineralized froth deposit seed metalliferous mineral.
In flotation concentrate technology, add a certain amount of flotation oil (foaming agent) in order to reclaim the granular metal mineral, and the mineralized froth that forms is loaded with a large amount of granular metal mineral, flow into thickener and sedimentation basin from flotation cell, along with mineralized froth the increasing of thickener and sedimentation basin with a large amount of foam of overflow outward, also take away a large amount of granular metal mineral simultaneously and lose.Run off for fear of the granular metal mineral, add a certain amount of precipitating reagent,, make granular metal mineral " flocculation ", to reduce metal loss as adopting the method for flocculant toward thickener or sedimentation basin.But in putting the bubble foam, this flocculant can only the aggregated particle metal in the oil film of mineralising factory foam, the mineral foam still exists, and the granular metal mineral can not be precipitated fully.
Purpose of the present invention is to adopt a kind of alkylbenzene sodium sulfonate (R that contains
SO
3Na) or alkyl sodium sulfonate (R-SO
3Na) surfactant joins the principle of adsorbing mutually with flotation oil in the mineralising bubble as defoamer, eliminates foam with the granular metal mineral precipitation, runs off to avoid the granular metal mineral.
In mineralized froth processing method of the present invention, adopt the method for a kind of surfactant as defoamer, in mineralized froth processing method in the past, adopt flocculant to make the method for granular metal mineral " flocculation ", fail to eliminate mineralized froth.
The present inventor finds by test, the surfactant that contains alkylbenzene sodium sulfonate or alkyl sodium sulfonate, the disappearance of bubbly water foam is dissolved in mutual absorption with flotation Shan in the mineralized froth, the granular metal mineral precipitation demonstrates extremely strong ability, based on above discovery, its principal character is that the inventor develops that to add this surfactant quantitative range be 2 kilograms-10 kilograms/ton.Another feature is the flotation concentrate mineralized froth that this defoamer is handled, and can be the mineralized froth of cupric, lead, zinc, molybdenum, gold, silver.
The invention provides table Xu activating agent (being alkylbenzene sodium sulfonate or alkyl sodium sulfonate) general molecular formula (R
SO
3Na or R-SO
3Na) be that two groups are arranged in the molecule: one has non-polar group (lipophilic group or be called the group of surging), and another has polar group (hydrophilic radical).Nonpolar group in the defoamer molecule is flotation oil (C not
10H
17OH) non-level property group adsorbs mutually, gos deep into together in the flotation solution with flotation oil under the effect of polar group (hydrophilic radical), makes mineralized froth lose flotation oil and disintegrates, and the granular metal mineral precipitate thereupon.The present invention shows that by experiment the flotation concentrate mineralized froth that this defoamer is handled can be the mineralized froth of cupric, lead, zinc, molybdenum, gold, silver.
Advantage of the present invention is:
1, flotation froth Lu has the concentrate mineralized froth of 1%-2%, is difficult for precipitation.In time handle (2.5-3 month), can reduce metal loss, the defoamer of every consumption monobasic can obtain 20 yuan-100 yuan metal.Metallic ore is different, usually ton concentrate defoamer 2-10 kilogram.
2, handle without this method, that part of concentrate foam that is difficult to precipitate can only reclaim 50%-60%, and moisture content is at 20%-25%.May be withdrawn into more than 98% with the method, moisture content is below 15%.
3, use surfactant as defoamer, for example: sodium alkyl benzene sulfonate or sodium alkyl sulfonate, raw material are mainly from petroleum product.So medicament is cheap, obtain easily, cost is low.In addition, this medicament does not all have influence to human body and environment.
4, because froth breaking rapidly, the granular metal mineral can precipitate rapidly, so just saved thickener in traditional dehydration active section, jet pump, filtering machine or the like.Like this, the dewatering process system is simplified greatly.Therefore, this technology utilization can also reduce investment 1/5th to newly-built small-sized ore dressing plant.
Owing to those are difficult for mobile plant equipment in the dehydration workshop section that saved time, this moves a formula ore dressing plant to foundation the technology possibility is provided.In other words, just can build miniature movable type ore dressing plant in full flourish from now on, solve fortune ore deposit, little ore deposit, mountain area difficulty.The grade that the mountain area can be abandoned lower " lean ore " turns waste into wealth.New technological means is provided developing mountain areas.
Embodiment of the present invention:
1,, be exactly regularly to handle (2.5--3 handled not layer foam of disposable thickener in individual month) to setting up the ore dressing plant of conventional dehydration pattern.Method: be the difficult precipitation foam on the thickener pond, collect in the tank diameter and (promote tank diameter 1.0m-1.5m), add the defoamer that is dissolved in water fully, subsequently the fine ore that is mixed with defoamer is changed over to flotation cell (0.6m--1.0m), common four flotation cells are just enough.Selected in floatation process, selected selected again.White foam in " mine tailing " is too much, is the defoamer surplus, and mineralized froth too much is the defoamer quantity not sufficient in " mine tailing ".General, there is not mineralized froth in " mine tailing ", a small amount of white bubble is advisable.
" mine tailing " enters the thickener sedimentation basin, and through the concentrate of defoaming treatment, foam all disappears, and the granular metal mineral sink at the bottom of the pond very soon.Go dehydration again, this moment essence mine dehydration, not only workman behaviour do conveniently, clean, agile, and concentrate moisture content descends, and improved the service life that filters cloth.
2,, be exactly to handle method: be (shown in Figure of description, to operate in process of production at any time to newly-built little dresser.A represents the concentrate mineralized froth among the figure, and b represents the defoamer that dissolved, and c represents that the concentrate of having handled well enters sedimentation basin).With the concentrate mineralized froth of selecting, inject the 1st flotation device.This flotation device is blowing air not, just stirs, and the part mineralized froth that lower floor sinks naturally enters concentrating and precipitating pond (container that can hold one day concentrate foam) by the flotation device dividing plate.The upper strata is difficult for the mineralized froth of precipitation and scrapes into the 5th flotation device.The foam trend as shown in the figure.
During operation, mainly see the mineralized froth that No. 2 grooves scrape, then the defoamer deficiency.If be white foam entirely, defoamer surplus then.General is that No. 2 the flotation device froth bed has a small amount of white bubble to be advisable.
The concentrate of handling has not contained oil vacuole, and moisture content permeates easily, evaporates, and therefore, pulls the granular metal mineral spirits out airing, is qualified products.
