Question

Is SiO2 is being extracted on industrial level any where or its only a part of laboratory work. Does any body know about its price? please tell me!

Dont tell me detail if its secret but only tell me that is SiO2 is being extracted from sand any where in this world?

Answer 1

Silicondioxyd is sand, so there is no need to extract it :P

Answer 2

SiO2 is the main ingredient of sand. Washing with pure water will remove some impurities; high heat will burn off others. Sand is used as raw material for glass. It is heated until it becomes soft and gooey, and shaped into whatever form desired. Some chemical impurities impart specific colors to the glass.

Answer 3

Silicon Dioxide (SiO2) IS sand. You don't have to extract it, you only have to clean it and melt it. Quartz is a purer version of the same thing and sand is broken down quartz.
I melt it in my backyard with added ingredients to make it melt at lower temperatures where it is called GLASS.
Hundreds of thousands of pounds of pure quartz are made every year for scientific tubing and solid state electronics. Most of the glassblowers listed in the Yellow Pages work with quartz rather than glass.

I really don't know. Sorry.
