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. |
