What is Silica Sand

Silica Sand is quartz that over time through the work of water and wind has been broken down into tiny granules Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays The resource is also used in industrial processing to make everyday items such as glass construction materials personal

Radioactivity in raw materials and end products in the

The high level of radioactivity can be explained on the basis of the following considerations uranium and thorium atoms are easily incorporated in the crystalline structure of the zircon furthermore zircon ores undergo an enrichment during sand processing which produces almost pure zirconium silicate

Radionuclide Transfer in the Zirconium Oxychloride
