Quartz Rock

Silica (SiO2) is the name given to lớn a group of minerals composed solely of silicon and oxygene. Found most commonly in the crystalline state, it also occurs in an amorphous khung resulting from weathering or plankton fossilization.

Silica svà deposits are most commonly surface-mined in open pit operations, but dredging và underground mining are also employed. Extracted ore undergoes considerable processing lớn increase the silica nội dung by reducing impurities. It is then dried & sized to lớn produce the optimum particle kích cỡ 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 & chemically inert và has a high melting point, attributable khổng lồ the strength of the bonds between the atoms. These are prized qualities in applications like foundries & filtration systems. Industrial sand’s strength, silinhỏ dioxide (SiO2) contribution, và non-reactive sầu properties make it an indispensable ingredient in the production of thousands of everyday products.

In its pulverized form, ground silica is required for production of fibreglass insulation & reinforcing glass fibers. Specialty glass applications include chạy thử tubes and other scientific tools, incandescent & fluorescent lamps, and television & computer CRT monitors.

Metal Casting: Industrial svà is an essential part of the ferrous & non-ferrous foundry industry. Metal parts ranging from engine blocks khổng lồ sink faucets are cast in a s& and clay mold to lớn produce the external shape, with a resin bonded core creating the desired internal shape. Silica’s high fusion point (1760°C) & low rate of thermal expansion produce stable cores & molds compatible with all pouring temperatures and alloy systems. Its chemical purity also helps prevent interaction with catalysts or curing rate of chemical binders. Following the casting process, core svà can be thermally or mechanically recycled to lớn produce new cores or molds.

Metal Production: Industrial svà plays a critical role in the production of a wide variety of ferrous & non-ferrous metals. In metal production, silica svà operates as a flux khổng lồ lower the melting point & viscosity of the slags khổng lồ make them more reactive & efficient. Lump silica is used either alone or in conjunction with lime to lớn achieve the desired base/acid ratio required for purification. These base metals can be further refined and modified with other ingredients to achieve sầu specific properties such as high strength, corrosion resistance, or electrical conductivity. Ferroalloys are essential to specialty steel production, and industrial svà is used by the steel and foundry industries for de-oxidation và grain refinement.

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 khổng lồ silinhỏ metal by coke in an arc furnace, khổng lồ produce the Si precursor of other chemical processes. Industrial sand is the main component in chemicals such as sodium silicate, silinhỏ tetrachloride, và silicon gels. These chemicals are used to produce household & industrial cleaners, to lớn manufacture fiber optics, và lớn remove impurities from cooking oil and brewed beverages.

Industrial sand is pumped down holes in deep well applications khổng lồ prop open rock fissures & increase the flow rate of natural gas or oil.

Oil and Gas Recovery: Known commonly as proppant, or “frac sand,” industrial sand is pumped down holes in deep well applications to prop open rochồng fissures và increase the flow rate of natural gas or oil. In this specialized application, round, whole grain deposits are used khổng lồ maximize permeability and prevent formation cuttings from entering the well bore. Silica’s hardness and its overall structural integrity combine to deliver the required crush resistance of the high pressures present in wells up to 2,450 metres deep. Its chemical purity is required to resist chemical attaông xã in corrosive environments.

General Industry Information

What is Fracking?

Fracking (fracing, hydraulic fracturing, or hydrofracking) is the most efficient method used to lớn access oil-bearing shales & limestones for the purpose of extracting oil & natural gas. Fracking is an unconventional extraction method in which hydrocarbon (oil/gas) is released from rock. In the fracking process, a vertical well is drilled for more than a kilometre & then continues horizontally once it reaches the shale layer (source rock oil or gas bearing formation). The well is drilled laterally for about 3,000 khổng lồ 5,000 feet. This creates a large enough surface area for oil or gas to flow in economic quantities. Cement is then pumped through the hole to surround the casing. Next, the plug-and-perf method creates multiple hydraulic fractures in the horizontal well. Water, sand, and lubricant are then pumped into the well at a very high pressure. The high-pressure fluid creates additional smaller fractures or channels in the shale through which oil và natural gas reserves flow more easily. The pressure is released & the proppants (sand) are left lodged inkhổng lồ the fractures, providing an efficient conduit for the movement of fluid from the reservoir lớn the wellbore, allowing an efficient escape for crude oil or natural gas flow. Most wells are able to produce for 20 khổng lồ 30 years without the requirement of additional fracturing.

Fracking aka the “Plug & Perf” method:

Frac Sand (often called “silica” or “silica sand”): A naturally occurring silica sand used as a proppant khổng lồ keep an induced hydraulic fracture open during the fracking process.

Frac S& Mineralogy: Frac svà must be greater than 99% quartz to be suitable for use as a proppant.

Alternative Proppants: Other alternatives to silica svà exist, including ceramic beads and resin-coated silica, but they are more costly lớn produce.
