Industrial grades of silica sand have a high content of silica (up to 99%) normally in the form of quartz, the most common crystalline form of Silicon Oxide. Silica sand is produced from loosely consolidated deposits and from weakly cemented sandstones. Silica is hard, chemically inert and has a high melting point, essential for many industries.
METHODS—Two hundred and forty seven patients with lung cancer and 795 control subjects were enrolled, all of whom had been employed in the German stone, quarrying, or ceramics industries. Smoking was used as a matching criterion. Exposure to silica was quantified by measurements, if available, or otherwise by industrial hygienists.

workers in the UK. The silica sand industry is engaged in quarrying and refining a product of high silica content and at quarries where silica flour and cristobalite are produced. Thus the possible respiratory risk may be higher than in other quarrying industries. During 1986 the UK Health and Safety
Silica. Silica sand deposits are normally exploited by quarrying and the material extracted may undergo considerable processing before sale. The objectives of processing are to reduce impurities and increase the grade of silica present and to produce the optimum .
Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted but quarries are also known by other names around the world: 'surface mine', 'pit', 'open pit' or 'opencast mine'.
Mining and Processing. With the deposits generally occurring at the surface, as is the case with the Dingo Hole Silica, mining the material is more akin to a rock quarry and therefore relatively low cost. The more limited the processing requirements, the lower the total costs of production.
