Description
The present invention relates to the processing method of mineral, comprise by selecting flocculation to do to reclaim nonmetallic mineral from the raw material of sludge and the non-homogeneous particle diameter that comprises sludge; Be particularly related to by the phosphate ores that is not removed sludge and reclaim phosphatic method.
The invention provides a kind of processing nonmetallic mineral, especially phosphatic improvement method for simplifying.This microcosmic salt is included in the ore, and wherein the primary granule particle diameter of ore to be processed is about 20 orders to colloidal particle size.Flocculation and floatation are to handle the known method of ore, but in known method, do not have a kind of successful method can be economical and processing simply contains the ore of effective component, and this active principle comprises trickle particle diameter, for example less than about 10 microns particle.
Particularly, phosphate ores contains a large amount of imperceptible particles, becomes comparatively difficult with regard to making processing and reclaiming required microcosmic salt.In the method for known processing phosphate ores,, be separated into ore in sand form component and abandoned mine mud part then at first with ore sizing.The grain diameter of ore in sand form component generally is about 20 orders to about 150 orders.Particle diameter 150 now to the fine particle of colloidal particle size be the abandoned mine mud part that goes out of use.Generally (it contains about 10% to 40% phosphate that is included in the original ore materials with this abandoned mine mud part.) enter the tailing pit that is unfavorable for environment.The method of known processing sludge generally comprises from bigger rough sand separation and goes out sludge, then with its processing.United States Patent (USP) 4,325 discloses that a kind of this patent is introduced by selecting flocculation to handle the method for phosphate ores particulate constituent for No. 709, with sodium metasilicate damping ore, adds water then earlier, then adds the flocculant of being made up of cellulose derivative.United States Patent (USP) has been introduced a kind of method 2, No. 660303, that is: the NaOH dispersant is added to sludge after, then add starch, selecting flocculation phosphate, and reclaim for separating.United States Patent (USP) 3,302, No. 785 introductions are handled Tennessee phosphate sludge by the anion froth flotation method, then remove the sludge of mine tailing, mine tailing and foam concentrate are converged, with the power supply stove raw material.Owing to lack greater than 325 purpose phosphate agglomerates in the sludge of Florida, so the inapplicable processing of said method Florida phosphate sludge.A.F.Colombo leans on middle announcement at the newspaper of the U.S. Department of Mines that is entitled as " dispersion and the flocculating properties of Florida microcosmic salt sludge ": use dispersant, then handle alkaline aqueous ore pulp (it is 8.5 to 10 phosphate abandoned mine mud that this ore pulp contains PH) as flocculant with H.D anion cornstarch, reclaim the phosphate product of 60-70%, upgrade and reach 2 to 5%, yet, there is not one piece to introduce and adopt the ore of non-homogeneous particle diameter to make raw material in the above-mentioned citing document, select the advantage of flocculation with non-ionic flocculant, in addition, do not have one piece of document introduction to cross and use hydrophobic selective flocculant.
Therefore, the objective of the invention is to can improve than general traditional method is the rate of recovery of metalliferous mineral.
Another object of the present invention is to provide a kind of improved method for simplifying, that is: adopt rough sand and above-mentioned abandoned mine mud, and use the hydrophobicity flocculant, makes initial phosphatic raw materials be selected the processing of flocculation process, thereby reclaims phosphate by phosphate ore.
Further aim of the present invention is to provide a kind of and reclaims phosphatic improvement method for simplifying from phosphate abandoned mine mud mine tailing.
Method of the present invention provides the higher overall recovery that reclaims the high-grade phosphate product from the ore of the non-homogeneous particle diameter that contains fine and colloidal particle size particle, and before can not get this high-recovery by the phosphatic processing technology in Florida.By method of the present invention, adopt the particle of 150 orders to colloidal particle size, improved the phosphate productive rate, reduced problem as the processing mine tailing that is run in the phosphate processing industry of present Florida.In addition, the ore sludge of 150 orders in the tailing pit to the colloidal particle size particle can be added on the bigger particle of particle diameter, be included in about phosphorus of 10% to 40% in the sludge with recovery.
The present invention relates to from being sized to approximately less than the ore separation and recovery nonmetallic mineral, especially phosphatic method of 20 orders to the non-homogeneous particle size range of colloidal solid.In the presence of dispersant, make ore become ore pulp through screening with alkaline aqueous solution.When using selectivity hydrophobicity flocculant, then (the most handy multistage method for floating, when handling ore pulp, nonmetallic mineral just obtains separating and reclaiming from ore with traditional method for floating.
In another embodiment of the present invention, previous with dispersant of selecting and flocculant processing by the isolated sludge of bigger ore particles, be recovered to a kind of high-grade phosphate product.
The present invention relates to from the especially phosphatic method of the ore recuperation nonmetallic mineral that contains above-mentioned mineral, wherein the particle diameter of ore is about 20 orders between the colloidal particle size, use method of the present invention, special disposal 150 orders are to the ore particulate of colloidal particle size, so that reclaim required nonmetallic mineral.
As the design of a broad sense, method step of the present invention comprises the screening ore, obtains the very little particle of about 20 order to 150 particle diameters, then, preferably spends the deionised water ore, and the adding of attached water forms ore pulp.The ratio of selected solid-liquid can be handled ore particles effectively.After handling with flocculant, produced enough frequent collision between particle, form callable agglomerate.Comparatively ideally be, the ratio of solid-liquid be at most 40% better be between 20% to 30%.To add the aqueous solution such as the dispersant of sodium metasilicate or NaOH.If adopt the dispersant of non-alkalescence, then the pH value with solution is adjusted at 9 to 11, preferably is about 10.After ore pulp and dispersant, add collection agent or other known trapping agents such as enuatrol, gasoline, make roughing ore particles tool hydrophobicity.Then, with optionally hydrophobic flocculation agent, preferably PEO (PEO) is added to ore pulp.PEO is assembled thinner ore particles selectively, makes its tool hydrophobicity.After air being fed ore pulp,, reclaim the nonmetallic mineral concentrate with the form of foam concentrate by common froth flotation step.
More specifically, with conventional method, the ore that will be suitable for obtaining required nonmetallic mineral pulverizes or grinding becomes to be generally less than 20 orders, comparatively it is desirable to, with ore grinding to less than 48 orders.The particle diameter distribution general about 78% of the ore of being pulverized is 20 order to 150 orders, and 22% is 150 orders.On the other hand, can produce required ore particle diameter by the method for ore extraction, perhaps required ore particle diameter is because the intrinsic physical property of ore determines.For example, in traditional Florida phosphate treated technology, generally do not grind phosphate ores, and sieve phosphate ores with 20 mesh sieves and cyclone separator, the ore size that is used to process is generally 20 order to 150 purpose ores in sand form, then forms discarded tailing less than the sludge of 150 order particle diameters.In the method for most preferred embodiment of the present invention, ore in sand form and sludge are formed the initial ore raw material together.
Then, the water or the aqueous solution make the ore through screening become ore pulp, and the percentage of solid particle is preferably between year 20% to 1,000,000 30%.Used water is preferably partly obtained from the sludge of raw material.Then, dispersant (for example sodium metasilicate and NaOH) is added in the ore pulp.The professional can understand, can adopt other dispersants with effect same.The amount that adds dispersant, be enough to making particle (comprising imperceptible particle) even, and farthest separate.Be preferably, the ratio of dispersant and solid agent particle be about ore to 2 per ton to 5 pounds, preferably the ratio with 2 to 3 pounds in ore per ton adds dispersant.The pH value of ore pulp should be alkalescence, better is in 9 to 11 scope, preferably is at least 10.Stir this ore pulp with the short time, preferably be about 1 to 3 minute during this period of time, with the total overall reaction thing in the mixed ore pulp fully.

Used sludge is the raw material of 150 order Tyler screens (Tyler Screen Sieve) in these examples, and ore in sand form is 20 to 150 purpose raw materials.
The general particle diameter of phosphate sludge is distributed as: 95% less than 20 microns, and 85% by 10 microns, and 60%-70% is narrower than 1 micron.Because P in whole particle size range
2O
5Concentration uniform often, have similar percentage so phosphate distributes.Can think that sludge is colloid basically.
The general particle diameter of ore in sand form is 20 order to 150 orders.
Example 2
Test, with estimate when the initiation material ore by 80%(weight) ore in sand form (20 to 150 order) and 20%(weight) and sludge (150 order) when forming to the influence of the phosphate rate of recovery.Making 700 gram materials wear into solid proportion is 25% ore pulp, and adds the dispersant sodium metasilicate by the amount of 3 pounds in ore per ton.Then, add the collection agent of forming by enuatrol, stir ore pulp powerfully by the amount of 1 to 2 pound in ore per ton.Then, the amount by 0.3 to 0.4 pound in ore per ton adds PEO.After slight the stirring, air is fed mixture, assemble rough machined foam concentrate.
Before the purification, in first rough machined phosphate concentrate of method for floating, its phosphatic rate of recovery is 79%.Behind the concentrate of having purified with said method, by analysis, the BPL in the final products is 65%, and the phosphatic rate of recovery is 68%.
Carry out complementary testing.Adopt identical test procedure, and the initial ratio of raw material is along with changing greater than 48 purpose ore in sand form raw material components of being pulverized, so as to discharge better the quartz of parcel/
The fluor-apatite particle.In this test, the phosphate rate of recovery in the rough machined phosphate concentrate is up to 93%.By analysis, the BPL of the product that process is purified is 67%, and the phosphate rate of recovery is 70%.
Test/mesh analysis shows that in whole particle size range, the phosphatic rate of recovery is all very high, and especially in the sludge scope of 400 purposes, the phosphatic rate of recovery reaches more than 92%.The dynamics research that the phosphate floatation is done shows that the phosphate sludge of flocculation obtains reclaiming prior to individual phosphate particle all the time.
Example 3
Carry out a series of test, with the variation of estimating sludge concentration in the initiation material ore influence to the phosphate rate of recovery.Adopt ore in sand form/sludge ratio of 90/10,80/20,70/30 and 60/40 respectively, the sludge percentage in the conversion initiation material ore.
For doing original contrast, use-case 1 described flocculation simultaneously and floatation and traditional flotation processing method are tested the raw ore of every batch of variation.Table 1 has illustrated by the resulting result of this test.
Example 4
Initiation material is 200g 150 purpose phosphate sludges.With raw material with go from water to be mixed into solid particle proportion be 15% ore pulp, with the amount of 6 pounds of/ton ores dispersant is added to said mixture.PH adjusted to be about 10.Stirred ore pulp 3 minutes with medium shearing force.Then, add flocculant Separan Mg 500 with 0.4 pound/ton amount.With the short time, flocculant and ore pulp are mixed and stirred, so that mix fully.Then, with solution left standstill, make two to be separated.These two mutually in, above one deck be the sludge phase, contain trickle clay particle, below one deck be the concentrate phase, phosphorous hydrochlorate flocculate.Sludge is removed as refuse and is not remake further processing processing.
Carry out the step that five continuous selections are flocculated and removed sludge.By analysis, the BPL in the flocculation concentrate is 30%, and the phosphatic rate of recovery surpasses 81%.The percentage by weight of the five batches of sludge products (refuse) that converged is 44, and BPL is that 8.7%(is equivalent to 4% P by analysis
2O
5).This shows that the discarded amount of clay product increases (only comparing with the discarded amount of the technology of sloughing sludge resulting 25% with the flocculation in a step with previous) greatly, and the corresponding increase of phosphatic grade in flocculation mutually.Thereby,, improved selection rate by clay flocculating phosphate particulate by sludge is contacted for a long time repeatedly with flocculant.
The test product is done various constituent analyses, to determine to select the distribution of essential mineral in the flocculation.The result of table 2 shows that by selecting flocculation, about 60% aluminium oxide (clay) and silica (quartz, feldspar) gangue component goes out of use in the abandoned mine mud.The calcium of phosphate mineral fluor-apatite and fluorine composition are between 78% and 83% in the flocculation concentrate.This is consistent with resulting 81% the BPL rate of recovery from this product.
Example 5
The multistage selection flucculation process of example 4 is applied to the similar sample of the phosphate sludge of another batch Florida production.After selecting flocculation and four steps of demineralization mud, by analysis, the BPL in the flocculation concentrate is 32%, and the phosphate rate of recovery surpasses 82%.By analysis, the BPL of whole sludges of being discarded reaches 14%, and the discarded rate of weight reaches 32%.Compare with the BPL of previous sample 20%, the BPL of discarded sludge sample is higher, reflects that the BPL of the primary sample of batch sample is about 26%.
Example 6
With traditional mechanical flotation machine and suck have the segmentation bubble tower, the phosphate particulate that example 5 is highly assembled carries out float test twice.In these trials, adopt traditional aliphatic acid, gasoline trapping agent, and in the mechanical flotation test, before flotation, also adopted PEO.After tested, the BPL of froth pulp reaches 35%, and only the BPL(a little more than flotation feed is 30%).In float test, be that the phosphatic rate of recovery that 20% initial sludge raw material obtains is respectively 55% and 44% by BPL with common mechanical flotation machine and tower.
Do further test with flocculence, but before flotation, do not slough earlier sludge, so that determine the influence of removing of clay sludge the phosphate flotation.In this case, phosphatic grade has only improved a bit, and the rate of recovery is very low.
