Oil Sands Extraction and Processing

Insitu extraction methods are used to recover bitumen that lies too deep beneath the surface for mining (greater than 75 metres underground). Currently, 80% of oil sands reserves are accessible via insitu techniques. Steam Assisted Gravity Drainage (SAGD) is currently the most widely used insitu recovery method. This method requires the drilling of two horizontal wells, one slightly higher ...

Athabasca Oil Sands Project, Canada

The first process to extract bitumen from oil sands on a commercial scale, developed in the 1920s by Dr Karl Clark, a scientist involved in hot water extraction, working for the Alberta Research Council. Ever since largescale mining of the sands began, variations of this approach have been used to separate aerated bitumen from the other constituents of oil sand within gravity settling vessels.

What is Lithium Extraction and How Does It Work?

 · By definition, lithium extraction is a set of chemical processes where lithium is isolated from a sample and converted to a saleable form of lithium, generally a stable yet readily convertible compound such as lithium carbonate. Most lithium extraction processes entail some form of mining to reach underground deposits of lithiumrich minerals or brines.

Hazard Alert: Worker Exposure to Silica during Countertop ...

Crystalline silica commonly occurs in nature as the mineral quartz, and is found in granite, sandstone, quartzite, various other rocks, and sand. Workers who inhale very small crystalline silica particles are at risk for silicosis – an incurable, progressively disabling . and sometimes fatal lung disease. Silicosis results in permanent lung damage. Silica . dust particles become trapped in ...

Worker Exposure to Silica during Hydraulic Fracturing

Silica dust cloud by worker delivering sand from sand mover to transfer belt. Crystalline silica is a common mineral found in the earth's crust. It occurs primarily as quartz and is a major component of the sand, clay and stone materials used to make every day products such as concrete, brick and glass.

Worker Exposure to Crystalline Silica During Hydraulic ...

 · Crystalline silica, in the form of sand ("frac sand"), plays a major role in the hydraulic fracturing process. Each stage of the fracking operation typically involves hundreds of thousands of pounds of "frac sand." The sand is used as a proppant to hold open the fissures created by hydraulic fracturing and allow the gas to flow out of the shale into the well. Moving, transporting and ...

The Dangers Risks of Taking Silica |

 · Silica pills and liquid formulas are marketed for their ability to strengthen the bones, improve skin health and repair damaged tissues. Most supplements contain silica — or silicon dioxide (SiO2) — derived from horsetail extract. This compound consists of silicon and oxygen and makes up about 59 percent of the earth's addition to its industrial uses, it's promoted as a natural ...

An Ancient Hazard in a 21st Century ...

 · In 2013, NIOSH researchers published exposure assessment results for respirable crystalline silica in oil and gas extraction (OGE) workers performing hydraulic fracturing. The results were noteworthy; a previously unidentified but serious occupational exposure hazard was discovered, and risks were significant‒in some cases, personal breathing zone exposures exceeded 10 times the .

Preventing Silicosis and Deaths From Sandblasting (92102 ...

Prohibit silica sand (or other substances containing more than 1% crystalline silica) as an abrasive blasting material and substitute less hazardous materials. Conduct air monitoring to measure worker exposures. Use containment methods such as blastcleaning machines and cabinets to control the hazard and protect adjacent workers from exposure.

Silica Statistics and Information

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) appliions; and for many other industrial uses. The specifiions for each use vary, but silica resources for most uses are

Silica

Silica is the basic component in sand and rock. It's in construction materials such as: Concrete, concrete block, cement, and mortar Masonry, tiles, brick, and refractory brick Granite, sand, fill dirt, and top soil Asphaltcontaining rock or stone Abrasive used for blasting Silica is the most common hazard on a work site. Any activity that ...
