| Conclusion
The high degree of purity of the quartz deposits of Wadi Mubarak area and their remarkable geochemical characteristic (high contents of SiO 2 and low contents of Al 2 O 3 , Fe 2 O 3 , CaO, MgO, Na 2 O, K 2 O and P 2 O 5 ) have nominated and qualified these deposits, even without beneficiation, to be used in hi-tech industries such as Aluminum alloy and Ferrosilicon alloy industries. The beneficiation process by froth Floatation has qualified the quartz deposits of Wadi Mubarak area to be used for the production of silicon carbide. 1. Moore P.
