Q1. How alumina manufactured and temprature.
Ans. 
Alumina is manufactured through the Bayer process, which involves extracting aluminum oxide from bauxite ore.
• Bauxite ore is crushed and mixed with sodium hydroxide to form a slurry

• The slurry is heated and pressurized to dissolve the aluminum oxide

• The resulting solution is cooled and filtered to remove impurities

• The aluminum oxide is then heated at high temperatures to form alumina

• The temperature required for this proce

Q2. Extractîon of Aluminiun
Ans. 
Extraction of aluminum involves the process of electrolysis of alumina.
• Aluminum is extracted from its ore, bauxite, through the Bayer process.

• The extracted alumina is then converted into aluminum through the Hall-Héroult process.

• Electrolysis is used to separate the aluminum from the oxygen in alumina.

• The process requires a large amount of electricity and is energy-intensive.
