There is a good reason for this:

Our raw sands are worked with optimum quality even at the very first stage. In the ensuing elaborate treatment processes the silica sand is washed and screened several times by wet-mechanical methods and by means of classification techniques. By means of further process stages in drying plants, screening plants and non-ferrous milling processes, our silica sand is then refined into the high-grade quality products that you are accustomed to receiving from us.
