Deep-mined quartz raw materials used in the TechniStone® technological process

Ing. Jiří Ludvík, Ing. Petra Dušková, Ing. Petr Pauliš

Technistone, a.s. processes mineral raw materials based on silica and various silicates for its production of hardened stone in Hradec Králové. A significant part of these quartz raw materials is mined in a deep way by Minerali Industriali. As part of the project in the TRIO research and development support program of the Ministry of Industry and Trade, project number: FV30114, the use of a new white silica raw material, mined in Scotland but finally modified for processing in Technistone by the domestic company Czech Silicat, was designed and verified. Another European quartz deposit deep-mined in Sondalo, Italy, is also described here.
