High Purity Silica Quartz in India

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.

Mining and Processing

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.
