Name of ore aluminum is found in

Q. I am stuck on a question. I need to find out what is the name of the ore which aluminum is found in.

Bauxite is the most widely used source of aluminum; there are several others. Check out this link: www.citycollegiate.com/aluminium1.htm

You are stuck because you did not make much of an effort. Open up any encyclopedia, look for aluminum and you will have an answer that you can use for a reference. Nothing that you get from a chat room should be used as gospel unless you know the qualifications of the person that responded. Example, If I told you that iron comes from Taconite, it would be true, but only one of the sources.

Hello Phoebe!

In my book, it's somewhere between baumé and Bavarian...

Good luck!

Hi Phoebe. Your mental tires must be bald today if you're stuck on that. I typed 'aluminum ore' into google and didn't even have to follow a single link! It says right in the abstracts of the first page hits: "The chief ore of aluminum is bauxite, a mixture of hydrated aluminum oxide (Al2O3·xH2O) and hydrated iron oxide (Fe2O3·xH2O)". Good luck.

Ms. Halliwell,

"The principal current source is the mineral bauxite, from which aluminum oxide is extracted and prepared for the smelter by crushing, grinding, chemical processing, and calcination." ASMI Metals Handbook Desk Edition, 1985.

As an ASMI member I should point out that members can access a full online copy of the Desk Edition at the website, www.asm-intl.org, and can buy all the books there too.

We sadly relate the news that Bill passed away on Jan. 29, 2010.

The most common aluminium ore is bauxite. There are plenty of web pages describing the extractive metallurgy of aluminium for its ores.
