1. Application The high purity quartz sand (HPQ) is one of main materials in the silica and silicon industry field.
Different avenues are open to exploit a high purity quartz deposit. In the last decades, high-tech applications using enriched quartz have evolved and the global supply does not follow the demand. United States, is the most important producers of HPQ sand. Quartz is used in a wide variety of applications, depending on its ore format and purity.
The main supplier of high purity quartz sand is the Unimin Company, USA that develops pegmatite deposits in Spruce Pine, North Carolina. The company, being provided with high quality raw material, has developed a very efficient beneficiation process that is continuously being improved and that provides stable high quality of the product.
Norwegian quartz has rather high content of aluminum and titanium and low content of iron, uranium and thorium. The company produces 4 grades of quartz concentrate in fractions of 0-150 micron and 100-300 micron. The company's quartz is used in optical industry. Russia has a good basis for high purity quartz production.
Baie Johan-Beetz's exceptional quartz ore deposit (high grade 99.6% SiO² ) with low contents of Boron (<0.2ppm) and Phosphorous (<0.2ppm)has the potential to become a disruptive force in the HPQ market. 02. Architectural applications The architectural qualities of pure natural quartz are among the most popular among architects and designers.
The quartz sand produced by the company is divided into several grades that have become world standards of high quality such as Iota-Standard, Iota-4, Iota-6, Iota-8 and so on. Another company in high purity quartz market is Coleman Quartz which mines rock crystal in Arkansas, USA. Annual supply varies between 350 and 500 tons.
