The high purity quartz raw material deposits are distributed in the United States, Norway, Australia, Russia, Mauritania, China, Canada and other seven countries.

U.S.A

Spuuspian deposit

The high purity quartz raw material mine of sperus Payne is located in the town of sprospein, Mitchell County, western North Carolina. The main diagenetic minerals of the ore are plagioclase, K-feldspar, quartz and dolomite, and almost no mafic minerals. The impurity element content of quartz is very low. After mechanical and chemical purification, the high purity and ultra pure quartz are mainly used in semiconductor wafer, precision optical glass, photovoltaic, lighting and other industries.

The mine supplies more than 90% of the world demand for high purity quartz sand, and even the only source for a long time. In 2009, the BBC called the site "the most strategic square acre on earth.".

Bouvier deposit

The bouville mine is located in bouville Town, rata County, northern Idaho. The purity of quartz crystal in ore is more than 99.9% and the content of Al2O3 and Fe2O3 is lower than 40% by electron probe analysis × 10-6(I-Minerals，2014)。 Beauville has a large amount of high-purity quartz resources. It can produce high-purity quartz sand by traditional flotation purification process similar to spurus Payne mine, and the difficulty of ore purification is low.

Norway

Delag deposit

The delag mining area is located near the village of drag, west of Tysfjord, Norland County, northern Norway, and consists of dozens of quartz bodies distributed in 5km2 square circle. The crystal is pure, the particle size is 6mm, and the fluid and solid inclusions are very rare. The impurity elements of Al, Ti, Li, B and other lattice elements all meet the quality requirements of high purity quartz raw materials.

Nesoden deposit

The nesoden mine is located in kvinherad, hodalan, southwest Norway. The quartz crystal in the ore is large and the size is between 1 μ The average value is 3mm between M and 3cm; Due to the influence of post Caledonian tectonic movement, quartz crystal is generally strongly recrystallized, fluid inclusions are widely developed, and solid inclusions such as dolomite, K-feldspar and calcite are also common.

Australia

Dengta deposit

The deposit is located in Georgetown District, North Queensland. The deposit is of hydrothermal quartz type, which consists of two peaks, which are like lighthouses in the East and West, and are about 440m higher than the surface, so it is named Dengta deposit. The ore is pure, translucent or milky white and massive, and is filled in the reverse fault in a nearly upright form. The results of ICP-OES test show that the ore purity of the East and west ore bodies is more than 99.90%, the main impurity elements Al, Ti, Fe, P, CA are all low. After simple mechanical purification, the purity can reach 99.95%, which proves that the Dengta deposit is a high-quality high-purity quartz raw material mine.

Tangbaoshan deposit

The deposit is located in Georgetown area, which is of hydrothermal vein quartz type, and is filled in the Paleoproterozoic metamorphic system fault zone in the northwest-south-east direction. The ore quality is very high, and the purity of SiO2 in situ can reach 99.99%.

At present, tangbaoshan deposit has not yet been mined and produced high purity quartz sand, but its proved and controlled resources are considerable and can be mined in open air; The purity of SiO2 from ore is over 99.99%, which makes the cost of mining and purification greatly reduced.

Baiquan and quartz mountain deposits

The ore deposits are of hydrothermal quartz type, and the mineralization process is similar to that of Dengta deposit. The quartz of Baiquan vein is produced in the biotite granodiorite of Silurian Devonian, and quartz in quartz mountain is vertical barrel in the biotite gneiss of the aensley metamorphic system of Proterozoic. The ore quality of Baiquan ore is excellent, the purity of raw material SiO2 is over 99.99%, and the inferred resource of high purity quartz is 1.5 million tons; The purity of quartz mountain ore raw material is more than 99.5%, and the predicted high purity quartz resources in accordance with JORC standard are 14million tons (solar quartz technologies, 2016), and the resource scale is huge.

Creswick deposit

The deposit is located in the Creswick District in South Central Victoria, Australia, 130km to the southeast and 20km from barrarat city in the south. The ore deposit is a type of gold tailings, which is composed of the abandoned tailings after gold rush mining in the 19th century. The ore is 6-200mm quartz gravel in tailings, which has excellent quality and low impurity element content, especially the content of B and P. The purity of SiO2 of high purity quartz sand can reach 99.995% after the traditional mechanical and chemical purification process is adopted by CSIRO.

Russia

Kashteme deposit

Kashtem deposit is located in kashtem City, Chelyabinsk, Russia, 100km to the southeast. The deposit is of hydrothermal quartz type and occurs in gneiss and migmatite of the uparchaean ufalemetamorphic complex. Gangue minerals mainly include feldspar, mica, carbonate, zircon, monazite, etc. The total length of the mine area is 15km, width 1-3km, area 20km2, and quartz reserves are 1.36 million tons. The main ore body used as high purity quartz material is No. 175 vein, which is distributed in the west side of Karabash from north to south. In 2014, imcmontan company conducted reserve assessment on vein 175 according to JORC standard, indicating that the reserve of high purity quartz raw material ore in the ore body was more than 500000 tons.

Saranbore deposit

The saranbore deposit is located in the northwest margin of the autonomous region of Russia, hant Manxi, which is translucent transparent and glassy; Gangue minerals contain a small amount of mica, calcite, chlorite, apatite and trace pyrite and rutile. The deposit is mainly composed of three mining areas, Dudu, nestshur and kusoika. The resources in Dudu mining area are the largest. According to the exploration reports of three mining areas in 2014, the resource amount available for high purity quartz is 330000 tons. In addition, there are many quartz veins that have not been explored outside the mining area, and the prospective resources may be more considerable.

Mauritania

Wumuaquinina deposit

The deposit is located in nuwadibu Bay Province, Western Mauritania. The deposit is of hydrothermal vein quartz type, and it is intrusive into granite gneiss and schist of regibat shield of Archean. The ore is translucent and smooth and transparent in light gray, and the SiO2 content of some samples is more than 99.8%. The ore body exposed on the surface is a large broken quartz gravel with a small amount of red soil covered. The inferred resources of quartz are 5-10 million tons, but due to the lack of borehole verification and test analysis and necessary beneficiation experiments, the resource quantity that can be used as high purity quartz raw materials is unknown.

Chami deposit

Chami deposit is located in the east of nuwadibuwan Province, 20km away from the umaquinina mine. The genesis, ore type, surrounding rock and occurrence characteristics of the deposit are similar to that of wumuaquinina mine, and the SiO2 content of the ore is 98% - 99.9%. Some ore samples were purified by anzapulan company, and the purity and quality can reach the standard of iota4.

Canada

Johnbiz high purity quartz raw material mine

In the coastal zone of johnbiz Bay, Southeast Quebec, Canada, 10 hydrothermal vein quartz bodies are exposed from the surface, namely John Byz high purity quartz raw material mine. The mining area is 68km from Port St Pierre in the West and 300km from the port of seven islands. The main areas in the area are Proterozoic quartz, gabbro, granitic gneiss. The results show that the SiO2 content of the ore is 98.7% - 99.6%, and the average content of impurity elements B and P are lower than 0.25, respectively × 10-6 and 0.2 × 10-6, which can be used to produce photovoltaic quartz crucible.
