Description
[technical field]
The invention belongs to technical field of beneficiation, and in particular to a kind of production method 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 production method of potassium feldspar, not by the processing method of the application
It is only capable of the principle active component of purification 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 production method of potassium feldspar, specifically includes the following steps:
S1, it desilts: low grade potassium feldspar raw ore is dug out, raw ore is sent on cleaning machine by screw conveyer, clearly
Spiraling in washing machine has screw type cleaning pipeline, and the surrounding for cleaning pipeline is evenly arranged with high-pressure nozzle, high-pressure nozzle water outlet
Towards cleaning insides of pipes, high-pressure nozzle water inlet connects water pipe, and water pipe connects high-pressure pump, when raw ore is delivered to the clear of cleaning machine
It washes in pipeline, opens high-pressure pump, water, which sprays to be rinsed the raw ore in cleaning pipeline from high-pressure nozzle, removes raw ore surface layer
Sludge；
S2, ball milling: by step S1, treated that raw ore is dehydrated, and is then fed into ball mill and carries out ball milling until partial size
Less than 0.5cm, ball milling mine is obtained；
S3, magnetic separation removal: the ball milling mine that step S2 is obtained is sent into high gradient magnetic separator and carries out magnetic separation, obtains concentrate slurry I；
S4, drying: concentrate slurry is added in drying oven and is dried to obtain solid-state concentrate；
S5, calcining: being transferred to calcining furnace for solid-state concentrate and calcine, and the temperature of calcining is 1300-1500 DEG C, during calcining
Nitrogen is added: the mixed gas that argon gas volume ratio is 1:2 fills calcining furnace；
S6, removal of impurities: carrying out ball milling for calcined ore, is milled to partial size less than 0.5cm, obtains ore pulp；
S7, flotation: being added sulfuric acid solution, then collecting agent and foaming agent is added in adjustment slurry pH to 6.2-6.8, receives
Collect froth pulp, obtains concentrate slurry II；
S8, oil removing: then concentrate slurry II is passed through into concentrate cyclone using fiber oil removing by microvesicle oil removal by air bubbling
Separation classification is carried out to ore pulp material, the ore pulp material of higher low stream concentration is collected, is then sent into concentration tower and is carried out dehydrating, obtain
To high-purity feldspar in powder.
It further illustrates, the magnetic field strength of the high gradient magnetic separator is 765-865KA/m, is sent into high gradient magnetic separator
Slurry flow velocity be 2.0-2.5cm/s.
It further illustrates, in the step s 7, 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 the step s 7, the foaming agent be petroleum sodium sulfonate, high alcohol oil, eucalyptus oil be obtained by mixing, matter
Amount is than being 4:9:11.
It further illustrates, in the step s 7, the dosage of collecting agent is 175-185g/t and the dosage of foaming agent is 55-75g/
t。
It further illustrates, in step s 8, the dehydration obtains the moisture content of high-purity feldspar in powder less than 5%.
It further illustrates, the screw pitch of the helical blade of front half section and the helical blade of second half section in the screw conveyor
Screw pitch ratio is 3-5:1.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
The technical solution of the application by high pressure washing raw ore, can remove stick together raw ore surface sludge and and can lead to
It crosses and constantly rinses the grease that can have on the outer surface to raw ore itself in screw type cleaning pipeline and removed together,
The obstruction of later period removal of impurities is prevented so as to improve the efficiency of post-processing impurity element, the efficiency of magnetic separation, hair can be improved after ball milling
12-14% is now improved by the removal rate that magnetic separation after ball milling removes magnetic impurity, in flotation step, the collecting agent phase of use
Than the prior art, the collecting agent of the application has excellent collecting ability, can be quickly irregular by the dispersion in slurry
The absorption of ore pulp solution, can speed the efficiency of removal, and the foaming agent of the application can quickly reduce the surface tension of water, catch from working as
Catch agent capture selectivity element float with mineral surface after foaming agent quickly after bubble and can be attached to what ore pulp captured
On element, as the effect of air bubble improves the efficiency of flotation.
