石英砂加工流程

工业上的石英砂原料品位越来越低，为满足工业上的需求，可以通过选矿工艺提高其品位。

主要有以下一些提纯方法：

1、擦洗脱泥。擦洗是指借助机械力和砂粒间的磨剥力来除去石英砂表面的薄膜铁、粘结及泥性杂质矿物和进一步擦碎未成单体的矿物集合体，再经分级作业达到进一步提纯石英砂的效果。目前主要有棒磨擦洗和机械擦洗。影响擦洗效果的主要因素为擦洗机的结构特点及配置形式；次要因素为擦洗时间、擦洗浓度（擦洗浓度一般以50%—60%为宜）。

2、磁选。磁选主要用于除去石英砂中的磁性矿物，如可以通过强磁性机除去赤铁矿、褐铁矿、黑云母等弱磁性矿物，而强磁性矿物如磁铁矿则可以通过弱磁选机除去。

3、浮选。浮选用于除去石英砂中的长石、云母等一些磁选无法除去的杂质，进一步提高其纯度。

4、酸浸。酸浸是利用石英不溶于酸（HF酸除外），而其它杂质矿物能被酸液溶解的特点，可以实现对石英的进一步提纯。

5、微生物浸出。是指利用微生物浸除石英砂颗粒表面的薄膜铁或浸染铁，这是新近发展起来的一种除铁技术。

产品包装：50公斤双层编织袋包装，出口吨袋包装，可按客户要求进行调整生产。

Introduction quartz sand
Quartz sａnd filter is made from natural quartz ore by crushing, screening, washing and other processing. Appearance of multi-prism, sphere, pure white, with high mechanical strength, interception capability, acid and good performance characteristics. , Is currently the most widely used in water treatment industry, the largest water purification materials, no impurities, compression wear, high mechanical strength, chemical stability, interception capability, high efficiency, long life cycle, suitable for single- , double filter tank, filters and ion exchanger, the targets are met (CJ/T43-2005) standards. Processing has refined quartz sand, pure quartz sand, quartz sａnd pickling, ordinary quartz sand, which can meet different user needs. Quartz sａnd act as a filter, like the penetration of water through the gravel into the ground, like those of suspended solids in the water block down, mainly for those fine suspended solids.
Classification of quartz sand
Quartz sａnd filter material as the application of quartz sａnd is combined with the filter container for trapping suspended solids in water colloidal particles of impurities, which act as a filter. Can be divided into the following categories:
1 ordinary quartz sand: mainly used in sewage treatment, three to five years with no problem, as long as the line to prevent the loss of quartz sand, is polluted does not matter, because the sewage treatment, sludge can be aerobic or anaerobic respiration the degradation of pollutants in wastewater.
2 refined quartz sand: used in water treatment, in the sａnd filter, generally two to three years to be replaced, usually the pollutant wrap quartz sａnd filter can no longer play a good role in the , only to be replaced. Quartz sａnd through Iso9001-2000 quality system certification. Value in the neutral and acidic water in the range are stable, but there is slightly soluble in alkaline water, chemical water treatment SiO2 increment does not exceed 2mg / L.
Refined quartz sａnd physical and chemical analysis:
Analysis Project Identification Data Analysis Project Identification Data Identification Data Analysis Project
/m3 bulk SiO2 content of % hydrochloric acid soluble rate of %
Mohs hardness 7 wear rate % Acid degree resistant to acid
Boiling point 2550℃Broken rate 5% Alkali resistance good alkali resistance
Melting point 1750℃​​Ash rate % Zn content of %
Proportion of porosity 43% other metal content does not exceed the national drinking water standards
Application of quartz sand
Quartz sａnd is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive and other industries. Available trucks, trains transport.

Six, mechanical: the main raw material foundry sand, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth, etc.).
Seven, electronics: high-purity silicon metal, communication with optical fiber.
Eight, rubber, plastics: filler (can improve the wear resistance).
IX Coatings: fillers (acid resistance of the coating can be improved).
Ten, aviation, space: its intrinsic molecular chain structure, variation of the crystal shape and lattice, it has a high temperature, thermal expansion coefficient, high insulation, corrosion resistance, the piezoelectric effect, the resonance effect and its unique optical properties.
Common Specifications:
1-2mm 2-4mm 4-8mm 8-16mm 16-32mm.
Packaging and storage of quartz sand
Quartz sａnd is woven bag, net weight 50KG, 25KG or tons of bags. Quartz sａnd with supporting materials and other media should not be stacked together. Quartz sａnd and other media not with other toxic and hazardous materials stacked together of contaminated items. Not leak days storage, dust pollution storage, generally the warranty period of ten years.
Quartz sａnd filter criteria:
Natural quartz deposits as raw materials, mining, crushing, washing, screening and other processed (high-purity quartz sａnd pickling), high mechanical strength, chemical stability meet the Ministry of Construction (CJ/T43-1999) standards.
Quartz sａnd processing flow
Industrial-grade quartz sａnd getting lower and lower raw material to meet the needs of the industry, you can beneficiation process to improve its taste.
Mainly the following purification methods:
1, scrub off the mud. Scrub refers to the use of mechanical force and grit grinding stripping force between the quartz sａnd to remove the surface film of iron, bonding and clay minerals and impurities further grater unpaired monomer mineral aggregates, and then by grading operations to achieve further purification quartz sａnd effect. Currently there are stick friction washing and mechanical scrubbing. The main factors affecting the effect of scrub scrubbing machine structural characteristics and configurations; minor factors scrub time, scrub concentration (scrub concentration is generally 50% -60% is appropriate).
2, magnetic separation. Quartz sａnd separator is mainly used for removing the magnetic minerals, such as by removing a strong magnetic hematite, limonite, biotite weakly magnetic minerals and strong magnetic minerals such as magnetite can be through weak magnetic separator removed.
3, the flotation. Flotation of quartz sａnd for the removal of feldspar, mica and some other magnetic impurities can not be removed, and further improve its purity.
4, acid leaching. Acid leaching is the use of quartz insoluble acid (HF acid except), and other impurities dissolved mineral acid can be characterized, can be achieved on quartz further purification.
5, microbial leaching. Refers to the use of microbial leaching addition of quartz sａnd grain surface film of iron or disseminated iron, which is a newly developed iron technology.
