Hello Megan!

I admit to being a bit confused- I don't see a question up there, only an assignment. : )

Anyway, the primary aluminum ore is bauxite. Aluminum oxide is usually extracted by the Bayer process, then converted to aluminum by the Hall-Heroult process. You can find out a lot on these topics in a good library. Yes, there are some fine web sites that deal with aluminum, but you'd spend less time reading and writing in a library than you would endlessly searching for tidbits of info on the internet. Plus, you won't have that annoying situation where the information goes directly from the internet to your printer and completely bypasses your brain.

Parentally yours,

Lee - good answer. Why do school kids think we are all totally naive? They must be made to think for themselves and not always opt for the soft option.
