Quality Assessment of Sand as Silicon Dioxide Collected from the Sudanese Areas (Bara, Elmtama and Karema) for Glass Industry

The silicon dioxide and microcline, samples were collected from the North Kordofan state Bara area, River Nile state Elmatama area and Karema. Then samples were subjected to X-ray diffractometer "XRD" accodrding to standard testMethods. Elemnts compostion was charactrized for all samples by X-ray florescence spectrometer "XRF". The particles size was carried out using sieve standards. Samples were acidified to improve the quality of silica. Silicon dioxide of Bara sand was found to be 100%, while that of Elmtama was 96.6% silicon dioxide and 3.4% microcline sandand for Karima sand 94% silicon dioxide and 6% microcline. The percentages of the silica sand were found to be 95.8% for Bara, 90.9% for Elmtama and 84.2% for karema. The iron oxide percentage for Bara was found 0.03%. The particle size for Bara, Karema and Elmtama were found to be (60, 100, 140mm), respectively.
