Ashapura's rounded to sub-rounded shaped silica sand grains (Supsil and Castsil) are naturally suitable for glass and foundry applications. Our ability to process narrow size controlled silica sand grains to achieve required AFS-GFN numbers for foundries sets Ashapura apart.
Refinements are carried out through mineral processing techniques such as magnetic separation and spiral gravity concentration to achieve lowest ferric impurities to suit advanced glass applications such as thin LED touch screen glasses.
