• WAVE OF GLOBAL SAND TRADE MAY BE DEPLETING BEACHES

    Sand is also pivotal for oil and gas companies for hydraulic fracking. Oil companies mix silica sand (also called "frac sand") with water and shoot it into shale rocks to break them apart and access the oil and natural gas inside. Companies recently discovered that using more silica sand makes the fracking process more efficient.

  • The chemistry of silica and its potential health benefits

    There are several water soluble forms of silica referred collectively to as silicic acid (ortho, meta, di, and trisilies), which are present in surface and well water in the range of 1100 mg/L. Orthosilicic acid is the form predominantly absorbed by humans and is found in numerous tissues including bone, tendons, aorta, liver and kidney.

  • Why isn't desert sand used in making silicon? Why only beach sand.

    You need sand with a very high silica or quartz content, so some desert sand could very well be used to make glass. But you also need to add other ingredients such as borax, washing soda, or a few other things to help it melt. Typically sand is harvested from places near water for convenience. 80. level 2.
