Description
Technical field
The present invention relates to a kind of natural siliceous sand impurity-removing methods, belong to quartz sand impurity removing technology field.
Background technology
Quartz sand is the broken quartz particles being process of quartz warp, and quartz is a kind of nonmetallic mineral, is one
Hard, wear-resisting, stable chemical performance the silicate mineral of kind, main mineral constituent is SiO2, the color of quartz sand is milky white
Color or semi-transparent clear shape, quartz sand are important industrial mineral raw material, and non-chemical dangerous material are widely used in glass, casting, pottery
The industry such as porcelain and fire proofing material, smelting duriron, flux for metallurgy, metallurgy, building, chemical industry, plastics, rubber, abrasive material, filtrate.
Since quartz mine is the blocky aggregate being made of with a large amount of impure minerals quartz, these impurity mines are removed
Object just must be such that these impure minerals are detached with quartz, become monomer, and common mode is exactly to use broken and disintegrating apparatus,
Quartz mine is ground into quartz sand, then removes impure mineral from quartz sand.Since quartz mine hardness is big, in broken, powder
In the broken stage, the abrasion of equipment is than more serious, therefore domestic many quartz sand factories make quartz mine all using roasting, water quenching method
Short texture after expanding with heat and contract with cold reduces the degree of wear of equipment during sand processed.But such mode is because of quartz mineral and length
When the mineral intergrowths such as stone, mica, it may appear that the initial melt temperature of so-called eutectic phenomenon, mixed system can be down to 700 DEG C
Left and right, and at present to the calcination temperature of quartz mine generally at 900 DEG C or so, it is fired in this way after ore produced
Partial melting, quartz surfaces will be firmly covered in very much by melting the nature of glass of formation, it is difficult to remove, due in these nature of glass
It is difficult to solve the problems, such as to be brought for the production of glass sand containing a large amount of elementary metal impurities.
And currently, China prepares and to use a large amount of acid during quartz sand and carry out pickling, and the quartz sand after pickling
Acid solution usually remains in quartz sand surface, can also influence subsequent manufacturing procedure, it is therefore desirable to carry out depickling to acid-washed quartz sand
Processing.A large amount of water are used only in traditional deacidification process to rinse, for before by a large amount of concentrated acids impregnate especially through hydrochloric acid or
Quartz sand after nitric acid acidwashing, often not enough thoroughly, remaining chlorion or nitrate ion etc. remain in acid-washed quartz for cleaning
Sand surface is but also acid-washed quartz sand color yellowing, the not good value for influencing product, it is also possible to its processing performance is influenced,
Therefore, there is an urgent need for finding a kind of acid stripping method of acid-washed quartz sand, the chlorion for remaining in acid-washed quartz sand surface can be thoroughly removed
Or the foreign ions such as nitrate ion, keep quartz sand purer, color is pure whiter.
Invention content
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of natural siliceous sand impurity-removing methods.
The present invention natural siliceous sand impurity-removing method be：Step 1: by the quartz sand that smashing fineness is 60-100 mesh
Grain carries out magnetic separation, magnetic field intensity 120-600mT using dry-type magnetic extractor；
Step 2: level-one flotation, is added foaming agent, blistering reaction 10-15min under weak acid environment in quartz mortar
Afterwards, material is sucked into flotation device, floatingly selects mica mineral；Secondary floatation adds under weakly alkaline environment in quartz mortar
Enter collecting agent, after reacting 5-15min, material is sucked into flotation device, floatingly selects feldspathoid；
Step 3: dewatered quartz sand is delivered to swaging machine, into swaging machine, catalyst and a concentration of 3%- is added in cycle
The addition of 18% oxalic acid acid solution, catalyst and oxalic acid acid solution is the 0.5%-3% into the quartz sand quality of swaging machine, stone
Sand is sufficiently mixed during scouring with catalyst and acid solution, then filters out the quartz sand through overpickling；
Step 4: deacidification, filters after quartz sand of the step 3 after overpickling is impregnated in sodium bicarbonate solution, spends first
Ionized water rinses 2-3 times, and deionized water is added in the quartz sand after flushing, obtains mixture, mixture is then inoculated with anti-nitre
Change bacterium, and agar block is added, agar block is isolated after closed standing, deionized water ultrasonic cleaning, ultrasound is then added
The frequency of wave is 55-75KHz, and speed of agitator 500-600r/min, scavenging period is 0 .5-1h；
Step 5: it is dry, quartz sand is packed into baking pan, oven temperature is set as 180 DEG C, is adjusted to automatically control, and is warming up to setting
Temperature keeps the temperature 3 hours, stops heating, and the taking-up of back pullout (BPO) in 1-2 hours is oven-dried material.
Preferably, the foaming agent is grouped as by the group of following mass parts：80-85 parts of ethylene oxide, surfactant
3-6 parts, 3-6 parts of polymer foam stabilizer, 5-12 parts of low carbon acid potassium, 5-12 parts of camphorated oil, 2-6 parts of precipitated calcium carbonate powder.
Further preferably, the foaming agent is grouped as by the group of following mass parts：82 parts of ethylene oxide, surfactant
5 parts, 5 parts of polymer foam stabilizer, 8 parts of low carbon acid potassium, 10 parts of camphorated oil, 4 parts of precipitated calcium carbonate powder.
Preferably, the collecting agent is made of the raw material of following parts by weight：2-5 parts of 1- butyl-pyridinium hydrochlorides,
2-5 parts of dodecyl sodium sulfate, 80-90 parts of kerosene, 2-5 parts of terpenic oil.
Further preferably, the collecting agent is made of the raw material of following parts by weight：3 parts of 1- butyl-pyridiniums hydrochloride,
3 parts of dodecyl sodium sulfate, 85 parts of kerosene, 3 parts of terpenic oil.
Beneficial effects of the present invention：This technique use flotation and magnetic selection method, can effectively remove quartz sand feldspar,
The non magnetic accompanying impurities such as mica and magnetic impurity, while the adhesive aluminium impurity for being present in quartz sand surface is also eliminated, it goes
Except rate height；And it can be by the chlorion for remaining in quartz sand surface of acid-washed quartz sand or nitrate ion etc. in dedoping step
Impurity cleans up, and keeps acid-washed quartz sand purer, and quality higher also makes the color of acid-washed quartz sand pure whiter.The letter of this technique
Single, impurity elimination effect is good, so that quartz sand purity is up to 99 .9% or more using such impurity-removing method, can be widely used in aviation,
In space flight, electronics, machinery and IT industries, as the raw material for preparing high, refined, peak products.
