High Purity Quartz Sand is used in specialist glass making facilities to make high purity quartzware products/tools used to smelt polysilicon as a basis for mono-crystalline solar PV and semiconductor grade wafers. High purity quartz sand is a necessity in the entire manufacturing chain.

In Far North Queensland Ultra HPQ owns a high purity quartz mine, Sugarbag Hill. With a 20+ year mine life, the company is in a strong position to supply high purity quartz materials to the high-tech markets for decades to come.

Ultra High Purity Quartz (HPQ) is a new entrant into the high purity quartz sand and powder market. The company was established by a management team that has spent the last ten years working in the sector.

The Sugarbag Hill quartz is a hydrothermal quartz deposit that has been drilled and assayed confirming a chemical signature that can be processed to high purity grades. The quartz body is approximately 800m long and has an estimated volume of greater than 2 million tonnes.

Ultra HPQ is looking to work with partners who share the vision of supporting the growth of solar PV as a renewable energy source and also those participants in the semiconductor industry with a demand for or interest in our plans to produce advanced quartz materials.

Silica, or more correctly silicon dioxide SiO2, is one of the most abundant compounds on the surface of the Earth, being most obvious as quartz and common sand. Silica has a multitude of uses depending on the degree of purity. Grades up to 99.5% SiO2 are used in the manufacture of glass, optical fibres and ceramics.

There are various definitions of High Purity Quartz (HPQ) relative to the total and elemental contamination. Whilst modern processing methods can remove much of the contamination, Naturally-occurring ultra-pure SiO2 (greater than 99.997%) which is suitable for production of high-purity fillers, silicon metal and use in solar panels and semi-conductors is geologically rare and commands a significant premium over the price of lower grader material. The very best processed silica rock can be offered to you. Deposits of this chemical quality and composition are rare and the largest known occurrence is in India.

The processing required to produce HPQ depends on the amount and type of impurities present and may include crushing, screening, floatation, acid-washes using hydrofluoric acid, magnetic separation and/or other physical, chemical and thermal techniques. Obviously, the lower the level of transitional elements and the more pure the material that is extracted from the ground, the less processing is required to produce a valuable product. With the deposits generally occurring at the surface, as is the case with the Dingo Hole Silica, mining the material is more akin to a rock quarry and therefore relatively low cost.

The global industry is dominated by a small number of players that are integrated from the mine through to the high end downstream processing. A good example is the Kakatiya Overseas in India, crushes, screens and mills the material to sand prior to flotation at the mine site before sending the material to Quarry for the final high end processing steps that remove the remaining unwanted deleterious elements.

Kakatiya Overseas is a leading producer and supplier of high quality and high purity Silica Quartz in various grades and grit sizes. We offer high volume supplies on a regular and consistent basis. Our deposits are in the famous and mineral rich Quartz belts of India. We are proudly recognized as one of the fastest growing suppliers of high quality and high purity Silica Quartz.

Kakatiya Overseas is a renowned name in the field of High Purity Silica Quartz for its finest quality. We have our own rich High Purity Silica Quartz quarries spread across South India with Admin.Office at Hyderabad India.
