Abstract
The present invention provides preparation process of hydrated silicon dioxide. Water quenched slag from iron smelting or copper smelting as material is acidolyzed and separated to obtain mixed hydrated silicic acid solution; and the mixed solution is processed through pH regulation, depurating, ageing, condensation, separation, washing and stoving to obtain hydrated silicon dioxide. The present invention has low cost, high utility and excellent environment and ecological effect.
