Question 1: Where is the best quartz sand origin? Ahu Town, a famous town in northern Jiangsu, is endowed with unique mineral resources and rich reserves of natural crystal, quartz stone, vermiculite, rutile and other minerals. Natural crystals are of high grade and have large reserves, accounting for about one-sixth of the country's total. Crystal processing has a long history and exquisite craftsmanship. It is the hometown of crystals in China. The crystal coffin of the great man *** was based on this. The national geological exploration department has proven that the reserves of high-quality quartz stone exceed 2.3 billion tons, and the silica content in quartz stone is as high as 99.8%. It is a domestic source of super-high-quality quartz sand. The high-purity quartz sand standards issued by the Ministry of Electronics Industry are based on the town’s quartz sand content. With vermiculite reserves of 22.3 million tons, it is the largest vermiculite mining belt in northern Jiangsu Province. The total reserves of rutile are 615,320 tons, with a content of 2.4-6.9% and a yield rate of 88% (the largest reserves in Asia). Associated with rutile are garnet and omphacite. The characteristics of these minerals are: comprehensive mineralization, large deposits, thick ore bodies, high grade, concentrated reserves, similar to open-pit type, and easy to mine.
Question 2: The main producing area of ??high-purity quartz sand. Nationally speaking, Donghai County, Jiangsu Province is the main producing area of ??quartz raw materials, occupying 80% of the national market. Its raw materials are famous throughout the country for their high purity and large output.
Question 3: Where is the origin of quartz? In addition to Shanghai and Tianjin, my country's crystal, quartz, and natural silica sand are produced in other provinces, cities, and autonomous regions. Guangdong, Guangxi, Qinghai, Fujian, Yunnan, Sichuan, Heilongjiang and other provinces and regions have better quality; Hainan and Jiangsu have the best quality. The main producing area of ??crystal and vein quartz in Jiangsu Province is Donghai County. Donghai County is rich in natural crystal and vein quartz reserves. According to the prediction of the Sixth Geological Team of Jiangsu Province, the natural crystal reserves are approximately 1,000 , with SiO2 content as high as 99.9983%. Its quality and reserves rank first in the country.
The mining of crystal and vein quartz in Donghai County has a long history. In 1958, a single crystal weighing 3.5 tons "Crystal King" was mined in Zhetang Village, Fangshan Town. In 1982, a single crystal weighing 2.1 tons was mined in Nanliu Village, Tuofeng Township. (all stored in the China Geological Museum in Beijing), attracting widespread attention at home and abroad. According to many years of statistical data from the Crystal Management Office of the Ministry of Geology, Donghai County’s crystal acquisition accounts for more than 50% of the national crystal production (Table 1 shows the crystal acquisition volume of Donghai County 105 Mine from 1973 to 1988), *** Chairman’s Crystal The raw materials for the coffin are provided by Donghai County, which is the famous "Crystal Hometown".
Since the reserves of crystal, vein quartz, quartz gravel, natural silica sand, quartzite and pink quartz ore are non-pillar mineral resources of our country’s national economy, they are also the largest unexplored reserves in our country. Non-metallic mineral deposits, therefore most of the country's reserves are estimated or unknown, and the principles of sustainable development must be taken into consideration in mining and use.
Question 4: Which quartz sand is better? Hello.
Quartz sand is divided into river sand and quartz sand.
The production areas are mainly in Gongyi, Henan, Hebei, and Shandong.
The quartz sand from Gongyi, Henan is better as quartz sand filter material
The quartz sand from Shandong, Hebei is relatively yellow and can be used for ornamental purposes. There are pros and cons to quartz sand in each location.
Please accept and thank you!

Introduction to quartz sand production line
1. Introduction to the basic process of the production line
First, the stone is made from coarse The crusher performs preliminary crushing, and then the coarse material is transported by a belt conveyor to the fine crusher for further crushing. The finely crushed stone enters the vibrating screen to screen out two types of stones that meet the needs of the sand making machine. The gravel with the feed particle size
is fed into the sand making machine, and the other part is returned to the fine crusher. Part of the stones fed into the sand making machine is made into sand, which is washed
After being washed by the sand machine (optional), it is made into finished sand. The other part...>>
Question 9: Where does the quartz sand, the raw material for glass, come from?
Nationwide, quartz mines are relatively widespread. Quartz sand is made from natural quartz ore. The quartz stone mined from the mine is processed through crushing, screening, washing and other processes. The appearance is polygonal, spherical, pure white, and has the characteristics of high mechanical strength, strong dirt interception ability, and good acid resistance. Generally, products with a fineness within 120 Mesh are called quartz sand. Products over 120Mesh are called quartz powder. High-quality mineral resources are mainly distributed in Jining, Inner Mongolia Autonomous Region, Fengyang in Anhui Province, Huanggang in Hubei Province, Baixin Quartz Sand Processing Factory and Fusheng Quartz Sand Processing Factory in Lingshou County, Hebei Province, with large output and high quality. In addition, there are also small amounts in Guangdong and Jiangxi distributed.
Question 10: What are the raw materials for producing quartz sand? There are two raw materials for producing quartz sand:
(1) It is made of natural river sand and sea sand and sieved. The advantages are local materials and low cost. The disadvantages are: due to long-term water erosion, the strength is reduced, the wear rate and breakage rate are high, the service life is short, and the mechanical strength is poor. These shortcomings are the primary factors affecting filtration speed.
(2) It is made from natural quartz deposits through crushing, screening and selection. It has the advantages of high density, high mechanical strength and pure color. It is suitable for drinking water filtration, circulating water treatment and Wastewater recycling.
