Silica sand was first used as a water filtering media in 1804, by John Gibb. The use of this media took over two decades to polish to perfection. The United Kingdom currently uses four ranks of silica sand for its water filtration processes. Silica sands that are appropriate for filtration have a sub-angular or round shape.

Within the world of asphalt, Rigsbee said, the lion’s share of silica dust comes from sweeping and milling operations. The most common containment method for sweeping and milling, Rigsbee said, is spraying water onto the dust. However, after OSHA passed 29 CFR 1926.1153 in 2017, reducing the amount of dust allowed from 250 micrograms per

Silica sand low in iron is much in demand for glass, ceramic and pottery use, and for many of these applications clean, white sand is desired. Impurities such as clay slime, iron stain, and heavy minerals including iron oxides, garnet, chromite, zircon, and other accessory minerals must not be present.
