SILICA SAND |
|
The grains found freely in nature have a loose character structure and with over 90% of SiO2, 7-15% clay (bentonite or kaolinitic clay) silica sand and with sintering temperature of 1500 C.
According to the intended use to the sands, they are subject to mineral processing operations according to their size and in terms of qualit. The result is used in many industries, particularly in the foundry industry.
