石英砂加工流程

工業(yè)上的石英砂原料品位越來越低，為滿足工業(yè)上的需求，可以通過選礦工藝提高其品位。

主要有以下一些提純方法：

1、擦洗脫泥。擦洗是指借助機械力和砂粒間的磨剝力來除去石英砂表面的薄膜鐵、粘結(jié)及泥性雜質(zhì)礦物和進一步擦碎未成單體的礦物集合體，再經(jīng)分級作業(yè)達到進一步提純石英砂的效果。目前主要有棒磨擦洗和機械擦洗。影響擦洗效果的主要因素為擦洗機的結(jié)構(gòu)特點及配置形式；次要因素為擦洗時間、擦洗濃度（擦洗濃度一般以50%—60%為宜）。

2、磁選。磁選主要用于除去石英砂中的磁性礦物，如可以通過強磁性機除去赤鐵礦、褐鐵礦、黑云母等弱磁性礦物，而強磁性礦物如磁鐵礦則可以通過弱磁選機除去。

3、浮選。浮選用于除去石英砂中的長石、云母等一些磁選無法除去的雜質(zhì)，進一步提高其純度。

4、酸浸。酸浸是利用石英不溶于酸（HF酸除外），而其它雜質(zhì)礦物能被酸液溶解的特點，可以實現(xiàn)對石英的進一步提純。

5、微生物浸出。是指利用微生物浸除石英砂顆粒表面的薄膜鐵或浸染鐵，這是新近發(fā)展起來的一種除鐵技術(shù)。

 產(chǎn)品包裝：50公斤雙層編織袋包裝，出口噸袋包裝，可按客戶要求進行調(diào)整生產(chǎn)。

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:

1.75t/m3 bulk SiO2 content of 99.5% hydrochloric acid soluble rate of 0.4%
Mohs hardness 7 wear rate 0.3% Acid degree resistant to acid
Boiling point 2550 ℃ Broken rate 0.35% Alkali resistance good alkali resistance
Melting point 1750 ℃ ??Ash rate 0.25% Zn content of 0.005%
Proportion of 2.65 porosity 43% other metal content does not exceed the national drinking water standards
Application of quartz sand

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.
