Silica sand may be produced from both unconsolidated sands and crushed sandstones. The sand is a product of mechanical and chemical weathering of quartz-bearing igneous and metamorphic rocks such as granites and some gneiss.
It is sometimes possible to produce a number of different grades of silica sand from a single quarry by selective quarrying of different parts of the deposit.
Metal Casting: Industrial sand is an essential part of the ferrous and non-ferrous foundry industry.
Metallurgical: Industrial sand plays a critical role in the production of a wide variety of ferrous and non-ferrous metals. In metal production, silica sand operates as a flux to lower the melting point and viscosity of the slag to make them more reactive and efficient.
Building Products: Industrial sand is the primary structural component in a wide variety of building and construction products.
