High grade silica is normally found in unconsolidated deposits below thin layers of overburden. It is also found as 'veins' of quartz within other rocks and these veins can be many metres thick. Silica sand deposits are normally exploited by quarrying and the material extracted may undergo considerable processing before sale.
