How is quartz sand different from ordinary sand?

Uses of quartz sand in water filtration.

What is quartz sand

Quartz sand, also known as silica sand, white sand or industrial sand, is composed of two main elements: silica and oxygen.

Although quartz is usually white or colorless, it can come in a variety of shades. The color of each sand deposit depends heavily on the type of minerals and rock fragments that make up the resource.

In order to be considered a quartz sand, the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criterion, it will be referred to as "ordinary" sand.




what is the difference between silica sand and regular sand? Ordinary sand, also known as feldspathic sand, brown sand or building sand, always contains some silica, but less than 95%. For example, a typical brown sand used in concrete applications may contain up to 80% SiO2, as well as varying amounts of iron, carbonate, potassium and other trace elements/minerals.

These "impurities" make ordinary sand more chemically reactive and often darker in color than quartz sand. Non-quartz sands (common sands) can also be various shades of white, pink, green and black - depending on the geological composition and geographic location of the sand deposit.

Quartz sand in water filtration.

One of the most common uses of quartz sand is for water filtration, whether treating well water or filtering tap water. Due to its uniform shape and size, quartz sand is an effective filter bed that consistently removes contaminants from water. In addition, it does not degrade when exposed to acidic chemicals.



Quartz sand has a wide range of uses in everyday life in several industries. If you would like more information, or if you are interested in ordering quartz sand, please contact WANCHENG today for a quote.
