When contaminating minerals are present the frac sands may come close to meeting API specifications, but still fail from one or two tests. For example, calcium carbonates, feldspars and magnetically susceptible minerals can cause crush test failings, or excessive acid solubility. Frac sand flowsheets
Mar 25, 2016· Frequently Asked Questions for General Industry. PDF version. On March 25, 2016, the Occupational Safety and Health Administration (OSHA) published a final rule regulating occupational exposure to respirable crystalline silica (silica) in general industry (the standard). 81 Fed. Reg. 16286.
When we consider the most common type of foundry sand, that is silica sand, both tests are related to the impurities normally found in the sand. Silica sand that is free of impurities will have a pH level of close to 7, which is, neutral on the acid and base pH scale. The ADV of this pure silica sand .

The Corporation''s silica sand deposit "Firebag Project" is located 95 km north of Fort McMurray and is accessible via Highway 63. The planned operation is for the production of industrial proppants for use in the hydraulic fracturing of oil and gas wells.
The acid solubility frac sand test determines how the frac sand reacts when coming into contact with acid. It is an indication of the amount of nonsilica contaminants in the frac sand. The API frac sand specs recommend the maximum percent (%) by weight of the frac sand that can be soluble in acid: 2% or less for frac sand mesh sizes 6/12 ...
Silica is an important topic in the construction industry with the new rule passed by OSHA, which reduced the permissible exposure limit (PEL) to 50 micrograms of respirable crystalline silica per cubic meter of air (μg/m3), averaged over an 8hour day.

FRAC Sand Lab Services. The Lonquist Sand Lab provides frac sand testing services to the oil and gas industry meeting American Petroleum Institute (API) and International Organization of Standardization (ISO) is capable of testing and analysis on both raw sand samples from the field and refined product ready to pump.
Silica sand is commonly used for abrasive blasting where reclaiming is not feasible, such as in unconfined abrasive blasting operations. Sand has a rather high breakdown rate, which can result in substantial dust generation. Worker exposure to free crystalline silica is of concern when silica sand is used for abrasive blasting.

What is silica? Silica is one of the most common naturally occurring elements on the planet. Silica, the mineral compound silicon dioxide (SiO2), is found in two forms crystalline or noncrystalline (also referred to as amorphous). Sand and quartz are common examples of crystalline silica.

What is Foundry Sand? • Foundry sand is a highquality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. • Foundry sands typically comprise of >80% highquality silica sand, 510% bentoniteclay, 2 to 5% water and less than 5% sea coal.
The API specifi cations set down for silica sand used in hydraulic fracturing, or fracing, are demanding. As Mark Zdunczyk of Continental Placer explains, suitable US deposits are limited and geology plays no small part in what makes the grade as a frac sand The facts of frac Courtesy Norsk Hydro.

Quantitative XRD Determination of Free Silica (Alpha Quartz) – Bulk Sample. For this test, a bulk sample is analyzed and the percent free silica (as alpha quartz) is reported. The free silica content is calculated by comparing the major quartz peak intensities of the sample with that of a .
Standard Test Method for Silica in Water 1 This standard is issued under the fixed designation D 859; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
WaySAND is a highquality regional frac sand, produced by Wayfinder Corp at its facility located 80km SE of Whitecourt on Hwy 43. This regional sand facility is closest to the Duvernay. The processing plant will be producing 100 mesh and 40/70 mesh frac sand. Both grades will be available from the facility near the Duvernay and at strategic locations around the Western Canadian Sedimentary Basin.
disabling and sometimes fatal lung disease. IARC and NTP have determined that crystalline silica can cause lung cancer in humans. Risk of injury is dependent on the duration and level of exposure. Follow OSHA or other relevant safety and health standards for the form of crystalline silica called Quartz. Current safety data sheet, containing safety
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. 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
