Sources

[edit]

Information in this article is based on http://minerals.usgs.gov/minerals/pubs/commodity/bauxite/ and on documents linked from there. This is a public domain ressource. -- JeLuF 11:43 Aug 28, 2002 (PDT)

Units

[edit]

What are the units... Billion tons? What kind of tons (metric/imperial). Can't make sense of this.. ...HE LIKES TO BREAK ERASERS....

Units used on the table are basically kilotonnes (metric system, 1000 x 1000 Kg; 1 tonne = 1000 Kg)... Assuming correct spelling you can tell the difference between tons and tonnes easily.--Staphylococcus 14:25, 20 January 2006 (UTC)[reply]

The units remain at problem’. The reserved table states it is in 1,000 Mg. Based purely on my understanding of the transport of bauxite, I think that must be 1,000 Metric tonnes, not megagrams (which is a Metric tonne if you are a math god, but not the usual nomenclature. Similarly the announcement by the Vietnamese Prime Minister is failing math. 1 Mt or tonne is 1,000 kg. 11,000 tonnes will in its entirety fit into the smallest bulker in International trade. It will fit into most coasters. Somebody needs to check the units being used and use the same one everywhere. Geekausaurus (talk) 10:59, 10 March 2020 (UTC)[reply]

Efficiency

[edit]

What percentage of this ore (Bauxite) eventuall becomes Aluminium?

I seem to remember reading somewhere that 4kg of bauzite is needed to make 1kg of aluminium. Indeed, a quick search here seems to confirm this. (the site says 4.1 tonnes bauxite --> 1 tonne Al) i wouldnt mind finding another source though. —deanos {ptaa*lgke} 06:09, 12 October 2005 (UTC)[reply]

"Bauxite with a penny" picture

[edit]

This is probably just inconsequential nitpicking, but that's not a penny. Pennies are a denomination of British currency. A better caption would be "Bauxite with a cent." Cent is the actual name for that denomination of American currency. I'm not quite sure why people commonly call it a "penny" when it's not even the same value as a penny.

—Preceding unsigned comment added by 24.254.177.36 (talk) 05:39, 31 July 2006
Or perhaps US penny. It's called a penny in the US and has a value of $0.01. Please, the British don't own the English language, 'nuff said - cheers, Vsmith 12:24, 31 July 2006 (UTC)[reply]
More to our inconsequential British nitpicker: Americans call the penny a penny because the Brits first introduced that currency before they were sent packing. Americans also use the word dollar (from German Taler), but I don't hear the Germans claim they own that word.
His point if that penny is not an official term for $0.01 USD, where it is for £0.01 GBP

"a common but unofficial name for the one-cent coin in the United States and in Canada, worth 1/100 of the dollar: see penny (U.S. coin), penny (Canadian coin). This word is not used by the United States Mint or the Royal Canadian Mint; they use cent." - penny

by using the term penny you are introducing ambiguity into wikipedia. --82.17.173.132 (talk) 18:40, 13 December 2007 (UTC)[reply]
http://www.mickstephenson.eu/enano/index.php/Special:DownloadFile/BauxiteUSGOVpath.jpg A penny is 20.32mm and a cent is 19.05mm given this if you were to work out the length of the line on this image based on the diameter of a cent you would get 92.72mm whereas a penny would give you the incorrect figure of 98.9mm, which is a difference of 6.18mm which is HARDLY nitpicking! this is obviously unnacceptable, i am taking the liberty of changing the caption myself --82.17.173.132 (talk) 22:06, 15 December 2007 (UTC)[reply]

World Production and Reserves

[edit]

I find this chart much more helpful than the article. I learn from it that Australia is by far the world's biggest producer. I also learn that the world supply it virtually unlimited while the actual use of the material is infinitesimal by comparison. The article reveals none of these facts.--dunnhaupt 18:28, 9 November 2006 (UTC)[reply]

I guess the production is limited by the amount of energy it takes. The article does not mention that (or any other cause) either. 130.89.228.82 21:47, 11 February 2007 (UTC)[reply]

Pronunciation?

[edit]

How does one pronounce bauxite? Is the 'x' silent, like it would be in French? dq 14:19, 27 November 2006 (UTC)[reply]

The 'x' is pronounced either as 'ks' or as a 'z'. Some dictionaries don't even mention the 'z' pronunciation though. I guess 'ks' is more common. User:130.89.228666.89.228.82 21:45, 11 February 2007 (UTC)[reply]
So you're saying it's most of the time pronounced "bow-ksite"? Weird. I thought since the word has a French basis it would be silent. dq 02:56, 13 February 2007 (UTC)[reply]
its generally, at least in the UK pronounced bork-site --82.17.173.132 (talk) 18:42, 13 December 2007 (UTC)[reply]

I dont understand bauxite, it makes no sense waht so ever to me. thats all folks! —Preceding unsigned comment added by 24.166.219.8 (talk) 19:11, 3 March 2008 (UTC)[reply]

Meriam-Webster provides an audio pronunciation of bauxite here. Sounds like "box-site" to me, although I learned to say "bawk-site" in several different geology courses (in the U.S.). Tim Ross (talk) 15:51, 29 July 2008 (UTC)[reply]

I've heard it pronounced both ways, the English-based "box-ite" (or perhaps "bawks-zite") and the French-based "bow-zite". Though the French version makes more sense (the name is based on the VERY COOL French town of Les Baux, "Leh Bow"), the English version seems to be prevalent. Dlchambers (talk) 14:03, 19 August 2008 (UTC)[reply]

bo-ite would be the 'french' way. no zeh sound in there. 86.131.94.47 (talk) 21:24, 4 November 2012 (UTC)[reply]

Bauxite classification and reserves

[edit]

Bauxites are aluminium-rich laterites which are residual rocks belonging to the sedimentary rock group. In geoscience they are not classified as soils and pedological terms as alcrete are useless in geology and only confusing. With respect to reserves and production of bauxites we should rely on the new data of U.S.G.S. and not cite hypothetic speculations on their life-span. For interested geoscientists I wrote a summary on laterites and lateritic ores under www.laterite.de --Schellat (talk) 11:37, 22 March 2008 (UTC)[reply]

Cryolite?

[edit]

The Cryolite article (http://en.wikipedia.org/wiki/Cryolite) says that Cryolite has been mostly exhausted, and thus other chemicals are now used as a flux. I think the article should reflect this but I'm no expert on which is right. —Preceding unsigned comment added by 128.3.62.254 (talk) 16:48, 3 April 2008 (UTC)[reply]

There was one Cryolite mine in Greeenland it is mined out; there was one rumor (which I have not seen confirmed) that there was another occurence in Siberia with about half the concentration. Theya re still using Cryolite to melt aluminium oxide at lower temperature than boiling point of aluminium (solving aluminiumoxide in cryolite lovers the melting point enough), what they are using is syntethic cryolite. Melting Bauxite is usually not done in industry, they dissolve it to remove impurities and percipiate out pure aluminium oxide.Seniorsag (talk) 13:55, 20 July 2012 (UTC)[reply]

aluminium vs. aluminum

[edit]

Almost all readers of this article are aware that aluminium and aluminum are the same thing. The former is used in British (and Australian?) English and the latter in Canadian and American. I just noticed a recent change whereby several uses of "aluminum" were changed to "aluminium", and researched the history of the article a bit, finding that it was initiated with the "um" spelling, but was converted to "ium" about a year later.

According to WP:ENGVAR, unless an article has a strong logical tie to some particular language version (for example, The Statue of Liberty or Manchester United), the version of English used in an article should be maintained. If we wish to follow the rules, I think we should be using aluminum. Tim Ross (talk) 11:20, 28 July 2008 (UTC)[reply]

But see WP:ALUM. For aluminium, caesium, and sulfur, the consensus is to use the IUPAC spelling. --Itub (talk) 09:23, 30 July 2008 (UTC)[reply]

Yes, of course, that makes very good sense. Thanks for pointing that out. Tim Ross (talk) 10:53, 30 July 2008 (UTC)[reply]

Bauxite

[edit]

What is the difference between Gibbsitic Bauxite & Boehmitic Bauxite & Diasporic Bauxite? (115.241.160.105 (talk) 05:59, 24 March 2009 (UTC))[reply]

The mineral composition differs: Boehmite Gibbsite Diaspore are the main minerals in that types of bauxite and give name to it.--Stone (talk) 11:08, 25 March 2009 (UTC)[reply]

Tech Talk

[edit]

I generally love Wikipedia. But this piece is an example of a handful of articles that fall short of helpful. I begins as if talking to an experienced mineralogist, with technical jargon, rather than a short paragraph for the layman. —Preceding unsigned comment added by 98.247.34.238 (talk) 15:57, 29 April 2009 (UTC)[reply]

Melting Bauxite

[edit]

A little research reveals that bauxite melts at 2000 degrees celcius. Aluminum melts at around 1220 celcius. What makes bauxite so hard to melt? —Preceding unsigned comment added by M00npirate (talkcontribs) 23:47, 11 February 2010 (UTC)[reply]

See also Cryolite above in this talk.Seniorsag (talk) 13:56, 20 July 2012 (UTC)[reply]
[edit]

I've had an attempt at fixing this, but to no avail, perhaps someone with better wiki-table-fu than me could give it try? -Oosh (talk) 12:35, 19 December 2013 (UTC)[reply]

Formation

[edit]

I have two questions about the first paragraph in the section "Formation", which now reads as follows:

Lateritic bauxites (silicate bauxites) are distinguished from karst bauxite ores (carbonate bauxites). The early discovered carbonate bauxites occur predominantly in Europe and Jamaica above carbonate rocks (limestone and dolomite), where they were formed by lateritic weathering and residual accumulation of intercalated clays or by clay dissolution residues of the limestone.

1) What is "the early discovered carbonate bauxites"? "Early" is an adjective, not an adverb. What noun is it modifying? Perhaps this could be re-worded so that it is clearer.

2) Regarding the last clause,

where they were formed by lateritic weathering and residual accumulation of intercalated clays or by clay dissolution residues of the limestone,

I can kind of figure out what the first part means (and I could use links to figure it out even more), but this phrase, "clay dissolution residues of the limestone", is just too dense for the average reader. Could this be explained just a bit? CorinneSD (talk) 23:18, 10 April 2014 (UTC)[reply]

Made an attempt at rewording ... hopefully better. rather needs a ref to support. Vsmith (talk) 01:00, 11 April 2014 (UTC)[reply]
It's much better. Thank you. CorinneSD (talk) 01:33, 11 April 2014 (UTC)[reply]

Incorrectly labelled video

[edit]

Video currently labelled as "Bauxite being digested by washing with a hot solution of sodium hydroxide at 175 °C (347 °F) under pressure at National Aluminium Company, Nalconagar, India." Is incorrectly labeled. The video actually depicts a hall-heroult electrolysis cell in operation. Video is still relevant and should remain, but label and title should be updated. A good image of a similar cell can be found at [1]https://knowledge.electrochem.org/encycl/art-a01-al-prod.htm in figure 3. Cdubsy (talk) 16:28, 29 October 2024 (UTC)[reply]

Hi @Cdubsy, I will ping the uploader @Psubhashish. Perhaps they can clarify. Commander Keane (talk) 23:55, 29 October 2024 (UTC)[reply]
Hi @Cdubsy and @Commander Keane, since I am not a subject expert in this topic, I'd correct the video description. Can I request either of you to change the Wikipedia article description so that I can align the video description accordingly? Psubhashish (talk) 03:19, 30 October 2024 (UTC)[reply]
