Answer 2

Answer:

In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. ... This treatment also dissolves silica, forming sodium silicate : 2 NaOH + SiO2 → Na2SiO3 + H2O. The other components of Bauxite, however, do not dissolve.
