Quartz - it all depends on the right raw meterial

Quartz (silicon dioxide - SiO2) is commonly found in nature and is one of the most important rock-forming minerals. It can be found in magmatic, metamorphous and sedimentary stone and deposits. Most naturally occurring silicon dioxide is in the form of trigonal quartz.
Quartz is hard, chemically inert and has a high melting point due to the strong attraction between its individual atoms. These are characteristics that are highly desirable in many industrial applications. Quartz is normally colourless or white, but also appears in various colours due to traces of other elements such as iron.
Deposits suitable for the extraction of raw quartz have occurred in nearly every period of earth’s geological history. Quartz sands are the result of various erosion processes. The individual grains may be sharp and angularor rounded, depending on how they were formed.The most important European deposits were created through sedimentary rock-forming processes in the Tertiary and Cretaceous periods.  They are 99% pure silicon dioxide.
From deposits like these, with sufficient quantities of high-quality quartz sand to last for several generations, Quarzwerke extracts valuable industrial minerals and supplies them to the processing industry. We offer the industrial mineral quartz as moist or dry sand, or ground into quartz flour.
