Description

It is a kind of to produce the technique that ceramics use potassium feldspar fine powder using potash feldspar tailings
Technical field
The present invention relates to ore treatment technical fields, it is more particularly related to which a kind of given birth to using potash feldspar tailings The technique that production ceramics use potassium feldspar fine powder.
Background technology
Potassium feldspar (K2O·Al203·6Si02) it is usually also referred to as orthoclase, belong to monoclinic system, is usually in flesh pink, white Or grey.Potassium feldspar series is mainly orthoclase, microcline, glassy feldspar etc..Potassium feldspar category monoclinic system is usually in flesh-coloured Huang It is white to wait colors.Density 2.54-2.57g/cm3, proportion 2.56~2.59, hardness 6, theoretical composition SiO264.7% Al2O318.4%, K2O16.9%.It has fusing point low (1150 ± 20 DEG C), and melting interval time is long, the spies such as melt viscosity height Point, is widely used in the industrial departments such as ceramic batch, ceramic glaze, glass, electroceramics, grinding-material and potash fertilizer processed is used.
Potassium feldspar does ceramic body dispensing in ceramic industry, the dosage of ceramic glaze accounts for 30%, remaining is for chemical industry, glass The other industries such as glass flux, frit Raw Materials, grinding materials and grinding tool, glass fibre, welding rod.With the development of economy, glass product, build It is increasing to build the dosages such as ceramics, potassium feldspar demand increasingly increases, wide market.
With greatly developing for ceramic industry, a large amount of consumption of potassium feldspar resource make potash feldspar ore reserves constantly reduce, The cost of exploitation is increasing, so potassium feldspar rise in price becomes inevitable.Supply falls short of demand for domestic high-quality potassium feldspar, at present ceramics Industrial high-quality potassium feldspar resource is from a large amount of imports of the country such as Korea, India.
It is recorded in view of above, nowadays potassium feldspar resource is reduced, and price increases so that ceramic cost increases, for some It is a larger burden for enterprise, and the tailing of some potassium feldspars is because its mine-containing amount is less, and impurity is more, it has not been convenient to carry Pure processing, therefore generally can all contain and abandon, but still contain more effective ore in tailing in fact, if can be by the part ore It uses, value is very considerable, therefore, in order to increase potash feldspar ore yield, reduces its cost, it would be desirable to by tailing profit It uses, we need to design a set of rationally efficient technique thus, and the potassium feldspar of better quality is obtained to be purified from tailing.
Invention content
Based on the above technical problem, ceramics potassium feldspar fine powder is produced using potash feldspar tailings the present invention provides a kind of Potash feldspar tailings can be purified to obtain potassium feldspar fine powder, to improve the utilization rate of potassium feldspar, increased by technique, the technique Potassium feldspar yield reduces its cost.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:
A kind of to produce the technique that ceramics use potassium feldspar fine powder using potash feldspar tailings, which includes the following steps:
Desliming of S1
Desliming is carried out to potash feldspar tailings using desliming bucket, removes the thin mud sand adhered in tailing or silt particle group;Removing A diameter of 0.01~10 μm to 0.01~25 μm of sludge;
The primary clear mud of S2
Potash feldspar tailings after desliming are passed through whirl screen, clear water is continually fed into whirl screen, it will be in potash feldspar tailings Ultra-fine silt particle powder cleaning filtering;
Bis- clear mud of S3
It filtered potash feldspar tailings will be cleaned is passed through air-dried feed bin and air-dry, further remove ultra-fine in potash feldspar tailings Silt particle powder, and remove excessive moisture;
S4 color sortings
Potash feldspar tailings after air-drying carry out color sorting in color selector, select satisfactory just finished product, substandard products and then reject;
S5 is ground
First finished product after color sorting is sent into ball mill and is ground crushing so that first finished product forms granularity more than 80 mesh Fine powder;
Bis- deslimings of S6
The fine powder that grinding is formed is fed again into desliming bucket desliming;
S7 magnetic separation
Fine powder after desliming is passed sequentially through into tablet magnetic separator and high gradient magnetic separator carries out magnetic separation, irony in fine powder is inhaled It is attached;
S8 is dehydrated
Fine powder is subjected to vacuum dehydration using vacuum dewatering apparatus, stops dehydration when water content is less than 30g/m3 in fine powder, Obtain finished product fine powder.
In the step S2 of process above, the temperature of clear water is between 30~42 DEG C.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:Present invention process is by by potassium Feldspar tailing classified, desliming, screening and purification, form available potassium feldspar fine powder, to realize waste utilization, reduce Potassium feldspar cost, improves potash feldspar ore yield, and obtained potassium feldspar fine powder can be directly used for ceramic body dispensing and pottery Glaze uses, and no longer needs to purchase raw material more, reduces cost of material.
