Reduction of Iron Content from Silica Sand by Scrubbing Process .

Dec 20, 2017 . In this research work, it was attempted to reduce the iron contents (Fe2O3) in silica from Shenin silica mine. This silica sand contains 93.75% SiO2, 0.44% Fe2O3, 2.78% Al2O3, and 0.08% TiO2 and the Fe2O3 has to be reduced to less than 0.08% or 0.02%. Four main factors (solid percent, scrubbing time,.

Silica & High Purity Quartz Information | Verdant Minerals Ltd

Obviously, the lower the level of transitional elements and the more pure the material that is extracted from the ground, the less processing is required to produce a valuable product. With the deposits generally occurring at the surface, as is the case with the Dingo Hole Silica, mining the material is more akin to a rock quarry.
