Silica Sand Manufacturing Process Silica Sand Extraction ...
Silica sand is a very important industrial material and is widely used in glass, refractory, metallurgy, and other industries. Generally, the main mineral of natural silica sand is quartz, and other impurity minerals are often accompanied. The mixing of these impurities reduces the value of silica sand and affects the quality of the product. Therefore, to meet the needs of industrial appli ions, it is usually necessary to remove impurities from silica sand.

Silica Sand - an overview ScienceDirect Topics
To make calcium sili e bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and “autoclaved” at about 170& 176;C 340& 176;F for several hours. Some gel, similar to the calcium sili e hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
