It removes the most possible impurities, while leaving the molecular structure of silica intact. The second acid attack by hydrochloric acid (HCl) or sulfuric acid (H2SO4) is intended to remove the residual impurities (Fe, Al, and Ti) in solution. Finally, this acid attack is followed by an alkaline attrition using a solution at 10% of sodium hydroxide (NaOH) in order to eliminate the residual metal from the sand
