How can TeO2 be separated from SiO2?

TeO2 (tellurium dioxide) can be separated from SiO2 (silicon dioxide) using various chemical and physical methods. One effective approach is leaching, where a suitable solvent or acid selectively dissolves TeO2 while leaving SiO2 largely unaffected. Another method involves flotation techniques, where differences in surface properties can be exploited to separate the two oxides. Additionally, thermal methods can be employed, as TeO2 may have different thermal stability compared to SiO2.
