Explore the difficulties of extracting aluminum from its ore, and how the vast quantities of heat and electricity generated by electrolysis allow this to happen.Key facts
- Aluminum is difficult to extract from the Earth's crust as it is highly reactive.
- Aluminum forms compounds that are very stable and difficult to separate.
- Bauxite is a natural ore of aluminum.
- Many chemical processes and reactions are used in the extraction of aluminum.
Transcript
Aluminum is the third most abundant element in the Earth's crust, but it's not an easy metal to extract.
It's found as a metal ore, meaning it's combined with other elements.
And aluminum's high reactivity means the compounds it forms are very stable and difficult to separate.
Bauxite
Bauxite is a natural ore …
