Why is it that aluminum is more costly than iron?
Aluminum is much more difficult to produce straight out of the earth. It naturally occurs in common earth minerals such as bauxite. A little Bayer processing turns it into aluminum oxide (Al2O3, aka alumina). This is itself a widely-used substance. The problem becomes separating the metallic aluminum from this point. The only known way to separate metallic aluminum from aluminum oxide in quantity is through the application of lots of electricity. It's a rather complicated, laborious, and energy-costly way to extract a metal...

How do you extract aluminum?
You need to pass an electric current throguh the molten aluminum oxide which is the ore for alumium and then u get pure aluminum at the bottom because its denser than aluminum oxide. Carbon dioxide is produced as well because the metals used to pass the electric current are carbon and the ocsigen reacts with the carbon to create carbon dioxide. ...

Why did Napoleon III use aluminum silverware?
He didn't use aluminum silverware. Aluminum objects were not produced in his life. He died in 1873.Most likely he used tin. It isn't until the late 1889 that a process was developed by Charles Martin Hall to make it into objects. As early as 1787 the ore was known to exist, but there was no way to extract it until 1825. ___ Yes Napoleon III did use aluminum utensils. He was very proud of them. "Napoleon III proudly displayed aluminum cutlery at his...

What is the function of cryolite in the extraction of aluminium?
It's used as a flux. It melts at a significantly lower temperature than aluminum oxide ores, but they will dissolve in molten cryolite. This means less energy is required to extract the aluminum from the ores than if they had to be heated to their melting temperatures. ...
