"rare earth"

[edit]

There is a sentence about them not actually being rare but if the article even mentions WHY they are called "rare earth" it sure hides it well. Why not have it stated the naming off the topic instead of only trivia like a town one of them were named after? 64.72.40.86 (talk) 13:28, 6 November 2022 (UTC)[reply]

See the last paragraph in the introduction:
Because of their geochemical properties, rare-earth elements are typically dispersed and not often found concentrated in rare-earth minerals. Consequently, economically exploitable ore deposits are sparse (i.e. "rare").
It should merit some treatment beyond that, though. Mindmatrix 14:34, 6 November 2022 (UTC)[reply]

Rare earths vs rare-earths

[edit]

It seems most of the sources use "rare earths" and not "rare-earths", yet the entire article is written with the hyphen.

Perhaps we need to open a discussion about which style the article should use. 71.11.5.2 (talk) 16:10, 28 July 2023 (UTC)[reply]

The article has been fixed, and hyphens are now only used as modifiers. 71.11.5.2 (talk) 13:44, 8 August 2023 (UTC)[reply]

A lot of new developments need to be added

[edit]

There have been numerous new geopolitical developments with regards to REEs as they become increasingly important with the rise of EVs. For instance, there is lots of pressure from the west to break China's monopoly in the industry. MP Materials is on the verge of producing REEs independently from China, Gina Rinehart has entered the industry, and both the Biden and Trump administrations have imposed tariffs on REEs from China. Should we include these developments in this entry? I am not even seeing anything about MP materials here. Frankserafini87 (talk) 21:19, 27 June 2024 (UTC)[reply]

Extreme misrepresentation of sources in "On human health"

[edit]

After reading some reviews of the toxicology of REEs I was disappointed to read "On human health" in this article. It is full of nonsense. Almost every single reference was completely misrepresented. I wonder if this should be investigated as something more than ignorance. Johnjbarton (talk) 23:20, 5 September 2024 (UTC)[reply]

Ok it looks like most of the content was added by a student in 2018. By their nature students need supervision: someone should have helped this student. Johnjbarton (talk) 23:58, 5 September 2024 (UTC)[reply]
Only going off the first reference, Hirano and Suzuki, it looks like the student skipped to the end and left with the takeaway of "Mortality studies reveal that RE are not highly toxic", ignoring the intratracheal and inhalation exposure effects. I imagine the same happened elsewhere. Reconrabbit 00:04, 6 September 2024 (UTC)[reply]
Sorry that was after my edits. I've changed this entire section. The inhalation effect leads to pneumoconiosis. I'll try to clarify that. Johnjbarton (talk) 01:19, 6 September 2024 (UTC)[reply]
Oh, I see now. I was wondering where the egregious issues were, but didn't realize you had made so many edits. Great! Reconrabbit 01:26, 6 September 2024 (UTC)[reply]
