Russia Nickel Export
MMC Norilsk Nickel is a privately held company that is deeply involved in the export of nickel from Russia. The sentence about "Russia using its 40% of the world's supply of nickel for its own domestic use" doesn't really make sense. The ore is smelted in Norilsk and the nickel is sold on the world market for the highest price and I am sure that Russia is not going to ever suffer a shortage of nickel, like Venezuela will never suffer a shortage of crude oil, no matter how much is sold. --McTrixie 11:41, 28 September 2006 (UTC)

"Metallurgical Industry of Russia": For 2006: ''Russia's nickel exports to countries outside the CIS in January-July increased by 5.5% on the year, to 143,600 metric tons, according to the federal customs service. Total nickel exports, including CIS states, were 143,900 tons.''

MMC NN produces about 250,000 metric tons per year total.--McTrixie 11:49, 28 September 2006 (UTC)

Phytoremediation
Is it relevant to add here some phytoremediation-related information relevant to nickel? There's some here: Hyperaccumulators table – 2 : Nickel, with particular attention to the notes at the end of the table, and to notes relevant to Streptanthus polygaloides and Thlaspi montanum. There are more to come of the same style, I just haven't developped that side for lack of where to put the info. I have the same question about quite a few metals, notably Cadmium (note with Tagetes erecta in Hyperaccumulators table – 1, and some), copper, lead, etc, incl. radionuclides. What/where do you think this should go? Basicdesign 05:30, 29 October 2006 (UTC)

Nickel

is it nickel is a recyclable material?

Extraction section
I have a few problems with the section on extraction: First, the article says "Most lateritic ores have traditionally been processed using pyrometallurgical techniques to produce a matte for further refining." I would say that most lateritic ores have been traditionally avoided, because they are so difficult to process! And the "traditional" matte smelting route is applied to sulfide ores, i.e. floation, partial roasting, electric or reverb smelting; or skip the partial roast and flash smelt. That's enough... I'll save my other quibbles with that section for laterBSMet94 06:20, 18 January 2007 (UTC) Revising my previous statemtent, I should have said that traditionally laterits have been avoided for production of elemental nickel. Obviously, the rotary kiln/electric furnace process has been around for quite a while in the production of ferronickel, which isn't exactly pure nickel production. Just thought I'd clarify my remarks. Isn't anyone going to correct that section, or are you waiting for me to do it? heheheh BSMet94 06:26, 16 February 2007 (UTC)

Radius of Nickel
I believe what you have in the article is the diameter rather than the radius. Check Helen G. Hansma et Al., DNA binding to Mica correlates with cationic radius: Assay by AFM, Biophysical Journal V. 70 April 1996 1933-1939. However, in the above they give the ionic radius and I think they refer to the hydrated radius but it is more likely than the one in the article in wikipedia anyway. —The preceding unsigned comment was added by 86.145.166.61 (talk • contribs).


 * Reference is atomic radii of the elements (data page). The articles use a set of data with consistent definitions taken from webelements.com, for what it's worth. Femto 14:52, 28 May 2007 (UTC)

The atomic radius is listed as 135 pm, but the Los Alamos Labs (which the article cites) lists the atomic radius as 124.6 pm. 99.233.162.203 (talk) 05:53, 7 January 2008 (UTC)

Canadian Nickel
I have found the Canadian Nickel after 1958 is not magnetic. It was also when Canada stopped making the polygon shaped one also. The article states it was magnetic on some dates up to 1989, I would like to know what those dates are. —Preceding unsigned comment added by 65.65.51.222 (talk) 23:33, 13 February 2008 (UTC)

Supply of Nickel Statement???
The last line in the article states "At current use rates, the supply of nickel is predicted to run out in 90 years."

That is patently absurd. Nickel makes up over 1.8% of the Earths mass. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=350422

I do not believe a single mention in a non-peer reviewed magazine warrants adding such an impossible to defend claim to this article. (P.S., I could not actually read the article by clicking on the link, but I can assure you the Earth will not be running out of nickel anytime soon, although the price may go up if deeper extraction is required.)

Confusing sentence
The sentence in the article under "extraction and purification" which says "In many stainless steel applications, the nickel can be taken directly in the 75% purity form, depending on the presence of any impurities." makes little sense, but I am not sure the best way to edit it. I believe what it is trying to say is that for use in making stainless steel, the 75% nickel extracted from ore using conventional roasting and reduction processes is of sufficient quality to produce the desired alloys with steel, but the statement "depending on the presence of any impurities" makes little sense. If the nickel is 75% pure, then there are certainly impurities present, in fact 25% of the material is (non-nickel) impurities. Should it say "depending on the composition of the impurities present"? Or is the statement that 75% pure nickel can be used to make stainless steel dubious? Theseeker4 (talk) 12:50, 8 October 2008 (UTC)

Mining Map
The map that shows mining of Nickle is wrong. It shows that the mines are in the east of Australia when in fact they are exclusively in the west. The pattern it shows for mines in Australia is the same as for iron, copper, uranium and aluminium. Whoever makes these maps please be more accurate

Nickel as an instrument of war
Since we were born in Canada 3 day before Pearl Harbour, we have been interested in the use of nickel ever since.

One of the first things we learned was that Canada and Russia controlled the world supply & price of nickel. And, not insignificantly, that nickel was a necessary element to fight any war, using guns. What that role has been, is now in Iraq, and will be in future wars is NOT even mentioned in this topic. Please, we are NOT suggesting that this is the time or place to argue "political" issues, only that one cannot discuss the 20th Century and it's wars, without discussing Nickel. And, we suggest, you can NOT cover Nickel, without at least once mentioning it's critical role in warfare.

Since this is my first view of this page, we are not prepared to suggest anything to you, yet. If it is already covered, please show me where. If it is not covered, we will suggest something for you to consider.

Allergic Reactions
Can we change to:

Nickel is the most ubiquitous contact allergen among children and adolescents. If its in contact with the skin like ear rings, blue jeans buttons and belts sensitised individuals may show an allergy to nickel affecting their skin.

 * I am currently still allergic to prolonged exposure to nickel, the metal here. Seeing as glasses are often made out of nickel, the ear portions that hold the glasses up have to be coated. At one point we could not find any, and therefore had to get stainless steel glasses, which of course, cost more. I cannot see why that under the toxicity section (where it mentions allergic reactions to nickel) that earrings are listed instead of glasses, seeing as many more people are inclined to wear glasses due to sensitive eyes than earrings. 96.42.46.42 (talk) 22:22, 2 August 2010 (UTC)

Confusion/Possible Edit Request
I was surprised to see a page locked after creating an account to make corrections, and further more to see the label GA on an article, must be a new system. A simple difference of information caught my attention. Wikipedia is most known for its user-friendly qualities. Though often said not to be a credible source by educators, its classification pages are often suggested by science teachers for its organization of taxonomy and elemental qualities. I find it essential that this mistake be corrected. Edit semi-protected A questionable contradiction with known theories, where the summary tables at the top right, under general properties, states that the Electron configuration of Nickel is [Ar]4s^1 3d^9; and though under Characteristics, the second paragraph states [Ar] 3d^8 4s^2 says it is incorrect, the Reference for direct investigation seems to also state that [Ar] 3d^8 4s^2 has the lower energy?

I think the following use of Nickel is called Rainey Nickel, but I do not know how to spell it.

Finely divided nickel is a catalyst for hydrogenating vegetable oils.

ok, it's awesome info n' all but i need to know what things have nickel in them!

I believe you are referring to "Raney Nickel" which is a trademarked Ni-Al alloy catalyst. The designation "Raney-type catalyst" is sometimes used to broadly describe Ni alloys with spongy, high-surface area structures. Reference to the Raney Nickel page could be added to this page. --Dhall27 (talk) 20:19, 28 June 2011 (UTC)

Most stable known nuclide
Section "Isotopes" states: 62Ni is the most stable known nuclide of all the existing elements, even exceeding the stability of 56Fe. This is not true, or at least misleading. That a nuclide has the highest binding energy per nucleon does not imply that it is the most stable.

This is most easily seen when looking at isobars. For example, tritium has a binding energy per nucleon of about 2.827 MeV, whereas helium-3 has only 2.573 MeV. I think that nobody would claim that tritium is more stable than helium-3 (to which it decays). Another example are carbon-14 (7520 MeV binding energy per nucleon) and its daughter nuclide nitrogen-14 (7476 MeV). --ulm (talk) 22:33, 3 July 2010 (UTC)


 * I agree. I think if we keep this statement, we need at least to link to a definition of "stability". Rwflammang (talk) 16:45, 24 April 2012 (UTC)


 * I suggest we just remove this sentence. We already have a clear and presumably correct statement in the second paragraph of the section, which says  Nickel-62 has the highest binding energy per nucleon of any isotope for any element (8.7946 Mev/nucleon). That should be sufficient. Dirac66 (talk) 17:44, 24 April 2012 (UTC)


 * If EE28Ni62 has the highest binding energy, that means that after the creation of EE28Ni58, with 2 extra neutrons, the nucleus was able to accumulate an additional 4 extra neutrons within the nucleus with even a lower binding energy to that minimum value. This and the Isotope EE20Ca40 indicate that the process of accumulation is evidently that of the accumulation of deuterons within a limiting mileau of available extra neutrons such as to act as a controlling factor over the atomic deuteron accumulation process.WFPM (talk) 15:43, 13 June 2012 (UTC) It is to be noted concerning this that the element 28Ni nickel is only 2 elements removed from the end of the 2 + 4 + 4 = 10 transition metal series, and that the 2 extra neutrons of EE29Ni58 could be due to the accumulation of neutrons rather than deuterons in the 29th and 30th locations for deuterons within the structure.WFPM (talk) 19:40, 14 June 2012 (UTC)


 * As a corollary to this we might note that in the next element 29Cu copper, the two stable isotopes are reported to be OE29Cu63, with 5 excess neutrons and OE29Cu65, with 7 excess neutrons, which indicates that the criteria for stability had increased to include the stability involved in the accumulation of the 4 more centrally located excess neutrons into the structure.WFPM (talk) 16:21, 13 June 2012 (UTC)

Magnetic properties
someone should perhaps add to the article that Ni is a quite interesting magnetic material, as it is a highly itinerant ferromagnet, shows extraordinary large longitudinal fluctuations of the local magnetic moment and due to these properties it has proven until recently extremely difficult to estimate its thermal properties through the standard methods of ab-initio thermodynamics. See e.g. Phys. Rev. B 75, 054402 (2007), Phys. Rev. B 64, 174402 (2001), Phys. Rev.

Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Nickel. Additional text was taken directly from USGS Nickel Statistics and Information, USGS Periodic Table - Nickel, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and WikiProject Elements but was reformatted and converted into SI units. --

Errors in production data?
As today Jan 29 2014, there is a discrepancy between the text and a table in World production section. Text is saying Russia is the largest producer in 2011, but it is only the third according to numbers in the table for 2011, as well as for 2012, also shown in the section. Below is likely outdated: They claim that Canada produces 30 percent of world nickel, and the implied claim that it is the biggest producer, seem to contradict other sources in the Internet. Russian nickel production is almost twice as high as Canada's, and most sources say that Russia is the biggest producer.

Dutch nickel
, could you add a reference link with the Dutch nickel? Unsourced it may be deleted. DePiep (talk) 17:07, 3 January 2015 (UTC)

The only references I have are internet ones: This one from a blog on Indonesian history is the most specific, in claiming they were ordered by Raffles when he was governor of Singapore http://blog.londoh.com/?itemid=1342 and even identifying the manufactures: Mr. Tabberer en Messrs Calley & Co in Birmingham.

Here's one on sale in the Dutch Royal Mint's website: http://www.knm.nl/Dubbele-wapenstuiver-1786-Utrecht-ZFr/nl/product/2272/ They are ofcourse the ultimate experts on Dutch coinage.

This site on old Dutch coinage also has a reference to a catalog of Verkade and a book of Zonnebloem, neither is in my possession: http://www.nederlandsemunten.nl/Virtuele_munten_verzameling/Provinciaal/Provincie_Utrecht_1581-1795/Verzameling_nikkelen_dubbele_wapenstuiver_Utrecht-Birmingham_1786.htm

Everywhere years of production are given as 1833-1844, so this is probably the first time nickel was used for coins. If you never seen nickel you will ofcourse think it's silver.

Nonsense statement not in source
''Nickel has been a component of coins since the mid-19th century. However, Birmingham was already using Dutch silver 18th century nickel coins forged in about 1833 (meant for trading in Malaya).''

Maybe something has been lost here, but the source does not mention Dutch coins. I have removed mention of the Dutch silver and the 18th century because it makes no sense, it is not supported by the RS, and I cannot reconstruct what was lost. If the earliest nickel coins were mid-19th century, there were no 18th century nickel coins, Dutch or otherwise. Grammar's Li'l Helper Talk 19:30, 27 May 2016 (UTC)

"Culture medium"?
What is meant by the phrase "culture medium" in this statement: The addition of ascorbate to the culture medium increased the intracellular ascorbate level and reversed both the metal-induced stabilization of HIF-1- and HIF-1α-dependent gene expression. Is the context of Petri dishes? If so, this statement needs more context. Thanks. Grammar's Li'l Helper Talk 21:30, 2 June 2016 (UTC)

TEM image in Properties section
This image is not of metallic nickel but rather of Ni(II) acetylacetonate inside of a single walled carbon nanotube, according to the source of the image, not just nickel as the caption of the image implies. That's confusing. Dakane2 (talk) 03:21, 12 July 2017 (UTC)

How is Nickel carcinogenic?
The official Dutch list of carcinogenic substances is full of Nickel compounds. . Do we have any idea through what mechanisms Nickel and these compounds are carcinogenic? PizzaMan (♨♨) 05:35, 17 July 2017 (UTC)


 * From IARC perspective it is an Group 2B carcinogen ie "possibly carcinogenic to humans". Even where a "definite" link is established this is often via statistical correlation to exposure. I have tried to find mechanisms for several carcinogens...(on google not in a laboratory!)...these can be as elusive as a cure for cancer. Bosley John Bosley (talk) 08:06, 17 July 2017 (UTC)


 * This is an outstanding question in the literature. According to this source, which would serve as a resource if you have access, nickel is primarily an epigenetic carcinogen. The details of specific cellular mechanisms are not completely known. LacMJ (talk) 18:55, 17 July 2017 (UTC)


 * This publication: How Tobacco Smoke Causes Disease mentions Nickel...don't think it answers you question but at least it mentions Nickel. Bosley John Bosley (talk) 08:21, 29 July 2017 (UTC)


 * Thank you for looking into it. The list I mentioned is aimed at employee safety, so the people who created that list will choose to err on the safe side. Yet, the amount of carcinogenic Nickel substances really caught my attention. Perhaps Nickel takes the place of other metal ions like Fe or Cu and thus disturbs transcription, or it causes low level inflammation like the dermal allergy. Here's a link to the list. https://zoek.officielebekendmakingen.nl/stcrt-2017-37689.html I'm going to edit the entry a bit, mentioning that Nickel compounds as a group are carcinogenic. Unfortunately, sources like this one also just say mechanism unclear: https://ntp.niehs.nih.gov/ntp/roc/content/profiles/nickel.pdf but they do clearly establish the carcinogenicity.

Adding sections
I'm new to Wikipedia, but if someone could tell me how to start a new section on the uses of Nickel, it would be a useful section.

To add a section simply go to the 'edit this page' tab at the top of the page. Reading the guidelines would also be a good idea.

Elements at center
Why is the center composed of iron and nickel? I added the only reason I could find, but it was reverted, so I put it back, with "Citation needed." Can we get a good one? I am not a scientist, just a guy who wants the answer. Yours, BeenAroundAWhile (talk) 02:00, 6 September 2017 (UTC)

''The amount of nickel which is allowed in products which come into contact with human skin is regulated by the European Union. In 2002 a report in the journal Nature researchers found amounts of nickel being emitted by 1 and 2 euro coins far in excess of those standards. This is believed to be due to a galvanic reaction.''
 * wouldn't the quantity of nickel exposure from dental braces be far above any contact from handling coins? Crusadeonilliteracy

I know that I can not wear many earings because nickel in the posts make my earlobes swell up.
 * This is an allergic reaction which often happens from contact with some metals. I believe a thing niobium plating resolved that problem.

The processing method png image is mislabelled. It has the compressor (cold) side of the engine using superalloys and investment casting, when it's mostly the hot side (turbine) that needs these technologies. — Preceding unsigned comment added by Laos (talk • contribs) 22:15, 8 June 2017 (UTC)

I am new to being a Wikieditor but chose to assess this article and was wondering if it was too early to incorporate data from 2017 in the article? I think it would be useful to have the data inputted to have it as accurate as possible. AnnikaET (talk) 17:58, 27 January 2018 (UTC)

Minor grammar correction
I revised "The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), that personified the fact that copper-nickel ores resisted refinement into copper." to "The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who personified the fact that copper-nickel ores resisted refinement into copper." If deemed inappropriate for some reason by more experienced reviewers please advise, and revert if you feel certain I erred. Cheers! --H Bruce Campbell (talk) 03:33, 20 February 2018 (UTC)

Aluminum
Nickel meta reacts exothermicly with Aluminum. Youtube has video of Nickel plated Aluminum foil and touch edge with torch and etire aluminum strip reacts. The exothermic reaction of Palladium and Aluminum is used to separate rocket stages. TaylorLeem (talk) 22:03, 31 August 2020 (UTC)

Lede way too long
The lede (lead section, before the Table of Contents) is absurdly long, detailed and rambling -- not the concise, few, summary paragraphs prescribed in WP:LEDE.

Strongly recommend that a NON-Ph.D. (who lives in the real world, and regularly holds conversations with ordinary people), overhaul that mess -- removing excessive detail, like: ...and moving those (and other overly specific or trivial) details to the appropriate existing (or new) sections -- and then re-word the lede into clear, concise, BASIC summary information about nickel, and its most significant roles in society. Remember, people, Wikipedia is for everyone -- not just us techie-nerds and trivia buffs.

Is the LME the only exchange which trades nickel?
Is the LME the only exchange which trades nickel? What other exchanges trade it, if any? If so, what prices did they post while the LME was not trading it? Just curious, because it would set a sort of base floor for Elliott Management's losses which they are suing for. If only LME trades it, and there are no other trades to base estimates on, then things are more difficult. Thanks in advance to anybody who knows. — Preceding unsigned comment added by Betathetapi454 (talk • contribs) 16:34, 6 June 2022 (UTC)
