摘要：A method is provided for treating silica sand scrubs (SSS) generated andaccumulated as waste in the chloride manufacturing process of titanium dioxide pigment.
A hydrothermal process is used to produce sodium silicate solutions of modulus 3.0 to3.8, and precipitated silicas. In some embodiments, the process uses two specific principalreaction stages. A sodium silicate solution having a low SiO:NaO molar ratio, in the rangefrom 2.0 to 2.8, is first produced by reaction of the SSS, as a cost-effective SiOsource, withaqueous caustic soda. The conversion of this intermediate sodium silicate solution of lowmodulus to a high SiO:NaO molar ratio is made possible by using a SiOsource that isprepared as precipitated amorphous silica from the intermediate sodium silicate solutionproduced above.
