Sand – especially Quartz - has high percentages of Silicon in the form of Silicon dioxide (SiO 2) and is the base ingredient for semiconductor manufacturing. Melted Silicon – scale: wafer level (~300mm / 12 inch) Silicon is purified in multiple steps to finally reach semiconductor manufacturing quality which is called Electronic Grade Silicon.

Flotation is mainly used to separate feldspar from silica sand, and can also be used to remove clay minerals such as mica and secondary iron from silica sand. The most typical process is to use hydrofluoric acid as the activator, and use an amine cationic collector for flotation under strong acidity (pH=2～3).
