Zirconium Silicate

The highest purity Zircon or Zirconium Silicate can be found in deposits close to the American, Australian and South African coasts. Zircon sand is separated from other minerals by ore dressing techniques during which strict controls are made to ensure the quality of the final product.

Depending on the application, Zircon sand may be calcined at a high temperature giving a stabilised product.

At one of the most sophisticated plants in Europe Zircon is processed and milled to the most stringent grading and particle sizes required.

A range of Zircon materials is available. However, for special applications, alternative particle sizes can be processed.
