6 Methods for Removing Iron From Silica Sand

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).
