Quartz sands in the chemical industry

Schlingmeier sands are distinguished by their high chemical and mineralogical purity. The sands are free of residuary flotation chemicals or other auxiliary agents since only physical preparation procedures are applied. Due to its very low content of aluminium, copper and nickel the sand is much in demand as a basic material for sodium silicate (water glass).

 

Please note our extremely pure grades displayed in light blue in the following table. They are characterized by their very low content of iron, titanium, aluminium, copper and nickel. These high-quality products satisfy even highest demands. All dry sands (T) can be supplied as blended grades.
