The Separation of a Mixture into Pure Substances
Heat the mixture to the boiling point (stop heating when boiling is observed), and stir the mixture with a stirring rod to make sure that all soluble material is dissolved. At the boiling point temperature, all benzoic acid and sodium chloride should be in solution. Thus, they have been separated from sand.

From Sand To Wafers
Purification starts by heating the sand with a reducing agent, carbon, to produce carbon monoxide and silicon. The product of this process, known as metallurgical grade silicon (MG-Si), may be as much as 99% pure. Additional processing is completed until ultrapure electronic grade silicon (EG-Si) is obtained. In addition to being very pure, …

How to make elemental silicon?
Silicon dioxide is a very thermodynamically stable compound.
