Question

explain the process of Bayer's process ​​

Answer 1

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. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process. ... 2 NaOH + SiO2 → Na2SiO3 + H2O.

Answer 2

Answer:

Bayer's process is used to obtain pure aluminium oxide from bauxite ore. The bauxite ore is concentrated by chemical separation. ... The bauxite ore is powdered and heated with sodium hydroxide under high pressure in the furnace. The aluminium oxide present in bauxite reacts with sodium Meta aluminate.
