What Is Silica Sand How Is It Different From Regular Sand?

Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.

What is Silica? Eurosil

The silica in the sand will normally be in the crystalline form of quartz. For industrial use, pure deposits of silica capable of yielding products of at least 95% SiO2 are required. Often much higher purity values are needed. Silica sand may be produced from sandstones, quartzite and loosely cemented or unconsolidated sand deposits.
