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
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.

May 09, 2010· I got some silica sand from the pool store and tested the PH of the run off when washing the sand. The PH was super high at about I don''t think I want to use this stuff in my tank. What other sand can I use that will not change the PH of the water? The water I used to wash the sand was from my R/O DI unit at about PH.

API 19C Proppant Testing; In addition to helping you test for frac sand, GEL can assist with testing drilling grade barite, drilling grade bentonite, and provides a variety of other testing services, including xray powder diffraction (XRD) testing, ICP analysis, acid solubility, heavy metals testing.
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.

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 ...
Frac Sand Products. American Silica''s East Cave City quarry has over 80 million tons of proven reserves of ordavacian sand commonly referred to as St. Peters sandstone, or within the oil and gas industry as northern white sand. Our reserves yield three grades of processed sand 30/50 mesh, 40/70 mesh, and 100 mesh.
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.
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 new standard requires employers to perform air quality testing for silica. The OSHA Silica Testing standard requires employers to: Quantify concentrations of silica that workers are exposed through air quality testing. Set an action level of 25 μg/m3 (micrograms of silica per cubic meter of air), averaged over an 8hr day.

Dissolved silica is found in almost all natural waters. Its presence is undesirable for many industrial uses because of scale formation. Highpressure boiler turbines are especially susceptible. Popular in many industrial applications, such as boiler turbines that are susceptible to scale; Provides fast results with an easytocarry test kit
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
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.
