Environmental Impacts

The four main types of gold mining include placer mining, hard-rock mining, byproduct mining, and gold ore processing that can all negatively impact the environment by changing the hydrology of streams, destroying land, and polluting soil and water with toxic chemicals such as mercury and cyanide. [1] [2] [3] [4] [5] [6]

Gold reactivity

Gold not reacting with KOH/NaOH in solution or molten state can be debated, typical etching with KOH will take time, visible in nano scales.

I would like to add the following information to the "Pollution" section, which is listed under the "Environmental Impact" in other metals page (eg https://www.search.com.vn/wiki/en/Copper#Environmental_impacts):

The estimated impact of gold mining on global warming was 12.5 tCO2eq per kg of gold in 2019[1]. By 2020, the BBC reported an increase to 16 tCO2eq per kg of gold[2]. Research111 (talk) 10:19, 20 October 2023 (UTC)

what gold uses for? 136.158.24.108 (talk) 13:06, 13 November 2023 (UTC)

Naming

It's incorrect. The word "gold" does not come from "aurum". It is Germanic. Grassynoel (talk) 21:54, 24 January 2024 (UTC)

Typo fix required:

This article is protected, so I can't fix it, so someone else will have to (I suppose if you like you could delete this note afterward, I don't know if that is customary). Anyway, in the section Chemistry/Rare oxidation states, the last sentence of the fourth paragraph: "It has been shown to unexpectedly stable at normal conditions" obviously should read "to be". I hate it when I find this sort of stuff in wiki articles, and fix them when I can. 2001:56A:F0E9:9B00:68D5:5DEB:2E68:F861 (talk) 01:04, 23 March 2024 (UTC)JustSomeWikiReader

Chemical reactivity in gaseous compounds

Although solid metallic Au is very unreactive, the opposite is true of gaseous gold. It very readily forms compounds with well over half the periodic table.

Some 40 years ago my DPhil research concerned the spectroscopy of the diatomic molecules CeO and Cu2. I learned then that more AuX compounds had been characterized with an element X other than, perhaps, oxygen which forms XO molecules. Hydrogen, forming HX, came a distant third.

If a sub-topic about this is decided to be worthwhile, I will try to dig up appropriate references and write the text. Xilman (talk) 16:39, 24 March 2024 (UTC)

Hi User:Xilman. I think content about that sort of topic would definitely be worth having. It's on-topic and seemingly not mentioned in the article we have now. And it's such a contrast to its behavior in the solid state (and the "common knowlege" based on it). I haven't looked at gold chemistry in many years so I don't know any of the current literature. DMacks (talk) 20:22, 24 March 2024 (UTC)
Hi Xilman: I see that there is also an article called Gold compounds that was created here in 2022 as a copy of the Gold#Chemistry section, and it remains nearly word-for-word identical in both articles. Ideally Gold compounds would be the in-depth article, with a summary here at Gold. Please add AuX information where you think it makes sense and I'd be glad to help organize. –MadeOfAtoms (talk) 04:23, 25 March 2024 (UTC)
Good idea. The sub-heading might be something simple like "Gaseous compounds". Xilman (talk) 15:20, 25 March 2024 (UTC)

Goldene

The researchers were able to create a layer of gold 1 atom thick. Do you think it's worth adding to the article? I'm not sure where.

jcubic (talk) 19:11, 27 April 2024 (UTC)

If the article had a section summarising the gold leaf article, it could go there? You would have to write it first . Or you could just add it to the gold leaf article? --𝕁𝕄𝔽 (talk) 11:29, 28 April 2024 (UTC)
