how to make silicon from sand

Polysilicon

Polysilicon – from Sand to Solar Cells, it Starts Here. The first stage to make polysilicon is to react SiO2 (in the form of quartzite) and Carbon in an arc furnace. This results in metallurgical grade silicon (MG Silicon). This MG silicon is then treated with HCl (hydrochloric acid)

How to Make Pure Sand (Silicon Dioxide) in a Lab

Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid. Place the orthosilicic acid into a heat-safe glass or porcelain dish and heat it over a burner flame for about 5 minutes. The orthosilicic acid dries to form silicon dioxide, SiO2, which is your pure sand.

Are computer chips made out of sand?

Scientifically speaking, the term "sand" is an expression of a certain grain size — 0.063 to 2 mm, to be precise. Computer chips are made of silicon, which is a semiconductor, andm in order to make the most efficient use of it, chip manufacturers use sand that contains as much silicon as possible.
