water glass was reported. Silica dissolution process was systematicallystudied,includingthethermodynamicana-lysis and the influence of calcium and aluminum on the leaching of amorphous silica. Simulation studies have shown that calcium and aluminum combine with silicon toformhydratedcalciumsilicate,silica–aluminagel,andsilica in the sand tailing. The level of silica in the leaching process reached the highest value of 90.40% for 15% nitric acid concentration. The silica levels for 5%-HNO3 and 10%-HNO3 were 89.35% and 89.42%, respectively. This increase due to nitric acid can effectively reduce impurity compounds such as Al2O3, P2O5, and TiO2.
