This following is a mistatement:

"The difficulty in the extraction of aluminium was in its high melting point (above 2000°C). Cryolite lowers the melting point to approximately 900°C to conserve energy"

The high melting point refers to the Oxide. I suggest the following correction:

"The difficulty in the extraction of aluminium was the oxides' high melting point (above 2000°C). Cryolite lowers the melting point to approximately 900°C to conserve energy"
