Alumina is obtained from bauxite through the Bayer process.
Bauxite is crushed and mixed with sodium hydroxide to form a slurry.
The slurry is heated and pressurized in a digester to dissolve the alumina content.
The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
There are four main types of cast iron: gray iron, white iron, ductile iron, and malleable iron.
Gray iron is the most common type and has excellent castability and good machinability.
White iron is very hard and brittle, often used for wear-resistant applications.
Ductile iron has high strength and ductility, making it suitable for a wide range of applications.
Malleable iron is heat-treated to improve its strength and du...
