  • 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) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

  • What is Silica Sand? - Select Sands Corp

    Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.

  • Method for Determining Crystalline Silica in Bulk Samples ...

    A systematic method of measuring crystalline silica (α-quartz) in bulk samples has been described. It involves homogenizing the bulk sample, sieving it to a <10 µm fraction, then analysing it by FT-IR. The method is capable of measuring crystalline silica down to 1% in routine bulk sample materials.
