Why We Should Choose Silica Sand for Business
What is Silica Sand?
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into
tiny granules. 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.
Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas
recovery in conventional and unconventional resource plays. The resource is also used in industrial
processing to make everyday items such as glass, construction materials, personal care products,
electronics, and even renewable materials.
Industrial sand is a term normally applied to high purity silica sand products with closely controlled
sizing. It is a more precise product than common concrete and asphalt gravels.
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
Silica (SiO2) is the name given to a group of minerals composed solely of silicon and oxygen. Found most
commonly in the crystalline state, it also occurs in an amorphous form resulting from weathering or
Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and
underground mining are also employed. Extracted ore undergoes considerable processing to increase
the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size
distribution for the intended application.
For industrial and manufacturing applications, deposits of silica-yielding products of at least 95% SiO2
are preferred. Silica is hard and chemically inert and has a high melting point, attributable to the
strength of the bonds between the atoms. These are prized qualities in applications like foundries and
filtration systems. Industrial sand’s strength, silicon dioxide (SiO2) contribution, and non-reactive
properties make it an indispensable ingredient in the production of thousands of everyday products.
Uses of Silica Sand
Glassmaking: Silica sand is the primary component of all types of standard and specialty glass. It
provides the essential SiO2 component of glass formulation, and its chemical purity is the primary
determinant of colour, clarity, and strength. Industrial sand is used to produce flat glass for building and
automotive use, container glass for foods and beverages, and tableware. In its pulverized form, ground
silica is required for production of fibreglass insulation and reinforcing glass fibers. Specialty glass
applications include test tubes and other scientific tools, incandescent and fluorescent lamps, and
television and computer CRT monitors.
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, sanitaryware, ornaments and wall and floor
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.
Chemical Production: Silicon-based chemicals are the foundation of thousands of everyday applications
ranging from food processing to soap and dye production. In this case, SiO2 is reduced to silicon metal
by coke in an arc furnace, to produce the Si precursor of other chemical processes. Industrial sand is the
main component in chemicals such as sodium silicate, silicon tetrachloride, and silicon gels. These
chemicals are used to produce household and industrial cleaners, to manufacture fiber optics, and to
remove impurities from cooking oil and brewed beverages.
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.
Industrial silica is used in a vast array of industries, the main ones being the glass, foundries,
construction, ceramics, and the chemical industry. Anand Talc is one of the most reliable Silica Sand
Manufacturer, Supplier in Rajasthan, India.
Silica in its finest form is also used as functional filler for paints, plastics, rubber, and silica sand is used in
water filtration and agriculture.
Crystalline silica is also irreplaceable in a series of high-tech applications, for example in optical data
transmission fibres and precision casting. It is also used in the metallurgical industry as the raw material
for silicon metal and ferrosilicon production. Another specialized application is in the oil extraction.
