Contact SupplierSilica Sand
Silicon and oxygen are the earth's two most abundant elements and together they make silica,
one of the earth's three most common rock forming minerals.
Silica occurs in three main crystalline forms. The principal occurrence is as the mineral quartz
but it also occurs in other rarer mineral forms known as tridymite and cristobalite. It is a very
durable mineral resistant to heat and chemical attack and it is these properties that have made it
industrially interesting to man.
The first industrial uses of crystalline silica were probably related to metallurgical and glass
making activities a few thousand years BC. It has continued to support human development
throughout history, being a key raw material in the industrial revolution especially in the glass,
foundry and ceramics industries. Silica contributes to today's information technology revolution
being used in the plastics of computer mouses and providing the raw material for silicon chips.
For industrial use, pure deposits of silica sand capable of yielding products of at least 95% silica
are required. Often much higher purity values are needed.
Uses of Silica Sand
The main end uses of silica sand are:
Glass
Silica is the major ingredient in virtually all types of glass. The principal glass products include
containers (bottles and jars), flat glass (windows, mirrors, vehicle glazing etc.), lighting glass
(light bulbs, fluorescent tubes, etc.), tableware (lead crystal, drinking glasses etc.), TV tubes and
screens, decorative glass, fibreglass, optical glass and vacuum flasks.
Foundry casting
Silica has a high melting point, 1610 degrees C. This enables castings to be produced by pouring
molten metal into moulds made out of silica sand.
Ceramics
Silica that has been ground to fine size is an ingredient of most clay bodies and is a major
constituent of ceramic glazes. Typical everyday products include tableware, sanitary ware,
ornaments and wall and floor tiles.
Filtration
Closely sized grades of silica sand is the principal filtration medium used by the water industry
to extract solids from wastewater.
Specialist building applications
The construction industry is founded on silica and there are a host of specialist applications
including silica and aerated concrete blocks, floor and roof tiles, flooring and rendering
compounds, white line markings, roofing felt and cement and resin injection systems.
Sports and leisure
Silica sand is used for equestrian surfaces, in artificial turf, golf course root zones and dressings,
football and cricket and other pitches and as play sands.
Other users
Silica has many other applications including the manufacture of chemicals and metals, fillers in
numerous products, plastic and otherwise, the manufacture of refractories, stimulating oil
production and as additives in agricultural and horticultural products. It is difficult to imagine a
life without silica!
Production of silica sand
High grade silica sand is usually found as unconsolidated deposits below thin layers of soil and
overburden. After quarrying, the sand often undergoes considerable processing before sale. The
processing may include washing and cleaning of the grains, sizing to remove coarse and very
fine fractions, and physical and chemical processes to remove iron, chromium and other
deleterious minerals. After processing, the sand may be dried and some applications require it to
be ground in ball mills to produce very fine material
