Abstract Silica sand is one of the most common varieties of sand, and it is used in industrial applications throughout the world. The application depends on the purity, grain size and chemical characteristics. In the present study, X-ray, chemical and petrographic analyses were used to study sand deposits from Tabuk area in Saudi Arabia.
Apr 01, 2018 Abstract. The characterization of natural silica from Tanah Datar region has been done due to variation of calcination temperature. Characterization is done using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). The results of the XRF test show that the content of silica
Mar 24, 2014 Abstract. Silica sand, (almost) pure quartz sand, is a valuable and scarce mineral resource within the shallow Dutch subsurface. High-grade deposits are exploited in the southeasternmost part of the country, as raw material for the glass, ceramic, chemical and other process industries. Dutch land-use policy requires that scarce mineral
