Abstract
The invention discloses a method for purifying quartz sand ore by using a physical method, which comprises the following steps: after quartz sand is roughly crushed by a jaw crusher and finely crushed by a sanding machine, wetly sieving the quartz sand with a 5mm vibration sieve; enabling -5mm quartz sand to enter desliming equipment for rough separation by a spiral classifier, fine separation by a swaging machine and scavenging and desliming by a small sand washing bucket, and sieving the quartz sand into products of a +60 mesh size fraction, a -60+140 mesh size fraction and a -140 mesh size fraction by a high-frequency vibration sieve, wherein the +60 mesh products and the -140 mesh products are byproducts; enabling the -60+140 mesh products to enter for deferrization (shaker and swaging machine); and after secondary separation and desliming, dehydrating and drying the products to obtain high-grade quartz sand, wherein the high-grade quartz sand contains 99.5-99.6% of SiO2 and less than 0.03% of Fe2O3, and the yield of the SiO2 is 90-95%. The high-grade quartz sand can be used as raw materials of solar quartz tubes; the +60 mesh materials obtained by sieving of the high-frequency sieve can be used as common glass sand; and the -140 mesh products can be directly sold after being ground into -325 mesh products. The invention has the advantages of good production environment, simple operation, low production cost, high purity of quartz sand, very low iron content, narrow size fraction intervals of quartz sand and the like, avoids the problem of environmental protection caused by flotation and pickling tail water treatment, and avoids the problem of dust pollution caused by dry sieving and dry grinding of the quartz sand.
Description
Technical field
The present invention relates to a kind of Yunnan quartz sand ore treatment method with comprehensive utilization, particularly a kind of with physics method purification Yunnan quartz sand ore, the method for irony thing and impurity belongs to the nonmetal ore-dressing field in the reduction quartz sand ore.
Background technology
Quartz sand claims silica sand again, is a kind of application nonmetallic ore raw material very widely.Quartz sand hardness 7, the crisp no cleavage of property, conchoidal fracture, greasy luster, relative density is 2.65, its chemistry, calorifics and mechanical performance have tangible anisotropy, are insoluble to acid, are slightly soluble in KOH solution, 1750 ℃ of fusing points.Color is creamy white, yellowish, brown and grey.Quartz has higher fire resistance, is divided into: common quartz sand, refining quartz sand, pickling quartz sand, glass sand etc.In quartz sand, essential mineral is quartzy, also often contains some other impure minerals in addition, and the impure mineral that wherein contains ferro element has: goethite, bloodstone, limonite, ilmenite, magnetic iron ore, tourmaline, hornblend, biotite etc.These ferrous contaminants or be embedded in the quartz particles, or invest quartz surfaces.Because the existence of these ferrous contaminants greatly reduces the use value of quartz sand, influence the quality of product, for example in glass production, ferrous contaminants all can produce bigger harm to the production and the quality of glass, particularly to the light transmission of macroscopic property in the glass smelting process and glass finished product.Therefore the content that improves the grade reduction ferro element of quartz sand in process of production just seems extremely important.In reality is produced, earlier raw material is washed desliming, adopt technologies such as mechanical scrub, magnetic separation, flotation, ultrasonic wave cleanings, acidleach to remove ferro element in the quartz sand, the use value of raising quartz sand again.
Purposes: make glass, refractory material, smelting duriron, flux for metallurgy, pottery, grinding-material, casting, quartz utilizes it that very strong acid-resisting medium etch ability is arranged under construction, is used for producing acid-resisting concrete and acid resisting mortar.Quartz sand is as the irreplaceable important foundation effect of the person of plaing in the production of silicon raw material and supply of the core material of silicon raw material.
Summary of the invention
The present invention is intended to overcome the defective of the control of granularity in the traditional handicraft and deironing, and a kind of cleaning of physics method purification stone sand, energy-conservation beneficiation method are provided.The present invention finishes according to the following steps: quartz sand is broken thick broken through jaw, the carefully broken back of sand shaker shakes to sieve with 5mm carries out wet screening,-5mm enters desliming device (spiral classifier, swaging machine, the little bucket of washed-out sand) desliming, the high frequency sieve that shakes is divided into (+60 orders ,-60+140 order ,-140 orders) three grades, + 60 orders and-140 orders are byproduct,-60+140 order enters deferrization (shaking table+swaging machine), product dewatered drying after the gravity treatment desliming just obtains high-grade quartz sand and (contains SiO
299.5 Fe ~ 99.6%,
2O
3＜0.03%), can be used as solar energy quartz pipe raw material.By high frequency sieve screening obtain+60 order materials, can be used as simple glass sand;-140 orders can be bought 1200 yuan/t through levigate again to-325 orders.
Described high frequency shake the sieve screen cloth be polyurethane screen.
Described high frequency shakes to sieve and is used for deironing, the preceding wet screening of oven dry.
The little bucket screen size＜1mm of described washed-out sand.
Described shaking table is a YBY-X cloud tin fiberglass fine sand shaking table.
Described qualified quartz ampoule is gone into stove product SiO
299.5 Fe ~ 99.6%,
2O
3＜0.03%, particle size range-60+140 order＞90% ,-140 order＜5%.
That the present invention has is simple to operate, equipment investment is little, production cost is low, the production time is short, production environment is friendly, wide adaptability, quartz sand purity height, iron content are contained little, quartz sand whiteness height, the interval characteristics such as narrow of quartz sand grade.In addition, present technique adopts wet screening in granularity control, reduced the harm (reducing the factor that causes that the workman changes anthraco-silicosis) of quartz sand powder dust pollution, and reduces the oven dry cost, for fields such as quartz glass tube production, building quartz sand provide qualified quality raw materials.
The present invention and traditional floatation, the acid-hatching of young eggs are relatively, have the production environment close friend, simple to operate, equipment investment is little, production cost is low, the production time is short, wide adaptability, quartz sand purity height, iron content are contained little, quartz sand whiteness height, the interval advantage such as narrow of quartz sand grade, the excessive power saving of dust pollution question, energy consumption for drying that environmental issue, equipment corrosion resistant problem, quartz sand dry screen, the dry grinding of having avoided flotation, acidleach tail water to handle bringing brings.Therefore, the present invention provides a kind of new method for handling refining quartz sand, realizes that environmental benefit, social benefit and economic benefit three are unified, has potential prospects for commercial application.
