Limonite

Limonite is not a mineral, as suggested by this article. Also, bridgmanite, (Mg,Fe)SiO3 - which is suggested to be the most common mineral in the Earth as a whole - is likely an important sink of Fe; there is no such mineral as "iron pyrite", but just pyrite. An important Fe mineral in the mantle is very likely wüstite-periclase solid solution; many igneous rocks also contain pyrrhotite as an important Fe carrier, the second one is pentlandite.

I've added some text to attempt to address these problems. Double sharp (talk) 03:35, 18 November 2016 (UTC)

Limonite has been a historically important mineral but is not longer classified as such. It has been described with hydrous Fe oxide ores (e.g. Minette (ore)) which are crucial for the history of steel making and iron mining (and for German French relationships). Imho no reason to delete it completely. but the wording has to be adapted. Polentarion Talk 17:49, 18 November 2016 (UTC)

Edits of today

I removed the following set of statements that were redundant or appear to be incorrect: It is the most important transition metal in all living organisms. Iron-proteins are found in all living organisms: archaeans, bacteria and eukaryotes, including humans. For example, the color of blood is due to hemoglobin, an iron-containing protein. As illustrated by hemoglobin, iron is often bound to cofactors, such as hemes, which are non-protein compounds, often involving metal ions, that are required for a protein's biological activity to happen. Iron is a necessary trace element found in nearly all living organisms. Iron-containing enzymes and proteins, often containing heme prosthetic groups, participate in many biological oxidations and in transport. I plan to delete this note in a few days. --Smokefoot (talk) 02:20, 17 February 2018 (UTC)

Possible removal from list

An entry in List of colors: A–F contained a link to this page.

The entry is :

• Iron

I don't see any evidence that this color is discussed in this article and plan to delete it from the list per this discussion: Talk:List_of_colors#New_approach_to_review_of_entries

If someone decides that this color should have a section in this article and it is added, I would appreciate a ping.--S Philbrick(Talk) 13:30, 22 August 2018 (UTC)
