Question

what is difference between bayers process and halls process​

Answer 1

Explanation:

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

Answer 2

Explanation:

Hey , here is ur answer

Dear friend, Beyer's process is used to purify bauxite and convert it into Alumina under low temperature and high pressure. While in Hall's process, the alumina is made good conductor of electricity by adding Cryolite(Na3AlF6) and flurospar (CaF2) and then electrolyzed to get Al-metal.
