Description
[technical field]
The invention belongs to technical field of beneficiation, and in particular to a kind of purification method of whitening of potassium feldspar.
[background technique]
Potassium feldspar is a kind of natural minerals containing K2O, Al2O3, SiO2 and containing impurity such as Fe2O3, and molecular formula is
K2O·Al2O3·6SiO2.Potassium feldspar is that ceramic industry manufactures china the primary raw material of glaze；It is one kind of glass mixture.
It can increase the viscosity and chemical stability of enamel, it may also be used for production enamel raw material, it is also possible to make insulation electroporcelain material, but potassium is long
Often some melanocratic minerals of association and potassium feldspar particle surface adsorb some pigment ions in stone ore object, influence raw ore and product
Whiteness reduces the quality of product, limits the application range of product, becomes potassium feldspar processing industry and adjusts the product mix, expands
The major obstacle in market.The main reason for leading to potassium feldspar coloring is due to wherein containing the colorings foreign ions such as iron, titanium.Therefore
Removal colouring ions, the research for improving its whiteness are of great significance.
[summary of the invention]
Goal of the invention of the invention is: providing a kind of purification method of whitening of potassium feldspar, passes through the processing side of the application
Method can not only purify the principle active component of potassium feldspar, moreover it is possible to which effective removal influences the impurity of potassium feldspar color.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of purification method of whitening of potassium feldspar, the specific steps are as follows:
S1, potassium feldspar desilt: low product valence potassium feldspar raw ore being dug out, the sludge removed in raw ore is rinsed using clear water；
S2, oil removing: the potassium feldspar raw ore after cleaning sludge is passed through into microvesicle oil removal by air bubbling, using fiber oil removing, then
Dehydration is dried；
S3, decomposition: dewatered raw ore is crushed, and is put into reaction tank, and it is dense that quality is then put into reaction tank
Degree is that the sulfuric acid solution of 18-35% impregnate 15-25 minutes, primary at interval of stirring in 1 minute, is subsequently added into distilled water dilution
Then slurry pH value into reaction tank is added 1/5 coconut shell flour of total weight, stirs evenly, carry out ultrasonic wave to 6.2-6.8
Processing 30-45 minutes；
S4, magnetic separation removal: magnetic separation is carried out to slurry by high gradient magnetic separator, the magnetic field strength of high gradient magnetic separator is
The flow velocity of 755-825KA/m, slurry are 2.5-4.5cm/s, are then separated by solid-liquid separation, obtain leached mud I and leachate I；
S5, flotation: by leachate I, sulfuric acid solution is added, then adjustment leached mud slurry pH value to 6.5-6.8 is added and catches
Agent and foaming agent are received, froth pulp is collected, flotation is obtained and leaches dreg slurry；
S6, removal of impurities: it is 10% sodium carbonate liquor that mass concentration, which is added, in leachate I, and adjusting leachate pH is 5.5, selection
Property precipitated iron, be then separated by solid-liquid separation, obtain leached mud II and leachate II, will in leachate II be added excess phosphoric acid dihydro
Potassium reacts 15-25 minutes, is then separated by solid-liquid separation, obtains leached mud III and leachate III；
S7, the preparation of high-purity potassium feldspar: the leachate III of leaching dreg slurry and step S6 that flotation in step S5 is obtained
It is mixed to get ore pulp material, separation classification is then carried out to ore pulp material by concentrate cyclone, collects the mine of higher low stream concentration
Slurry is then sent into concentration tower and is carried out dehydrating, obtains high-purity potassium feldspar.
It further illustrates, in step s3, the raw ore is crushed, and the granularity of broken raw ore is less than 0.5cm.
It further illustrates, in step s3,285-310 hertz of the power of the ultrasonic wave.
It further illustrates, in the step s 7, the dehydration obtains the moisture content of high-purity potassium feldspar less than 5%.
It further illustrates, in step s 5, the collecting agent is lauryl ammonium chloride, diesel oil, the mixing of acetic acid lauryl amine
And it obtains, mass ratio 11:8:13.
Further illustrate, in step s 5, foaming agent be petroleum sodium sulfonate, high alcohol oil, eucalyptus oil be obtained by mixing, mass ratio
For 4:9:11.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
By carrying out preventing the obstruction of later period removal of impurities except sludge and the grease carried so as to improve post-processing to raw ore
The efficiency of impurity element, by crushing raw ore acid adding carry out impregnate can by the dissolution of the active metal element selectivity in miberal powder,
And the rate and the extent of reaction of coconut shell flour control reaction are added under certain pH value, it can promote under the collective effect of ultrasonic wave
Charge inactive element sepatation in miberal powder, magnetic separation removes magnetic impurity element, but dust removal rate cannot reach
100%, leachate I and leachate I are obtained after separation, leachate I can further remove mica by flotation circuit and iron is miscellaneous
Matter, further removes ferro element and titanium elements in leachate I, and the leachate I also main component element containing potassium feldspar removes
Continue recycling after miscellaneous and mixed with dreg slurry is leached, by obtaining high-purity potassium feldspar after being further concentrated.In flotation step,
Compared with prior art, the collecting agent of the application has excellent collecting ability to the collecting agent of use, can quickly will be in slurry
Dispersion irregular ore pulp solution absorption, the efficiency of removal can be speeded, the foaming agent of the application can quickly reduce water
Surface tension after foaming agent energy after capturing the element floating of selectivity when agent for capturing with mineral surface quickly bubble and is adhered to
In on the element that ore pulp captures, as the effect of air bubble improves the efficiency of flotation.
