An earlier version of this article was adapted from the public domain USGS Minerals Information publication "Platinum-Group Metals Statistics and Information", available online at http://minerals.usgs.gov/minerals/pubs/commodity/platinum/ Please update as necessary.
The section "Sources of platinum group metals" (taken from Wikipedia element articles) is unnecessarily repetitive, and could do with a good copyedit. --

I don't care it's OK I guess —Preceding unsigned comment added by 71.14.16.70 ( talk) 22:54, 9 October 2009 (UTC)
The non-similarity to the iron group metals (iron, cobalt, nickel) and its causes should be explained. Normally you'd expect them to be chemically similar, since they are located above the platinum group in the periodic system. -- 92.229.88.194 ( talk) 11:33, 25 March 2010 (UTC)

The article contains the following statement: "They have similar physical and chemical properties,...". This is repeated in the Palladium lede. In fact there are innumerable differences in reactivity and physical properties between these metals. Just for example, ruthenium and osmium form highly reactive volatile tetroxides, while the other four do not. Platinum is soluble in Aqua regia while iridium is not. Platinum is soft and the most ductile of metals while iridium and osmium are very hard and brittle. The melting point of Pd is an unremarkable 1555°C while that of Osmium is 3033°C, making it 4th highest element. What, then is the rationale for the statement that they are similiar. On the face of it their properties look very highly individualistic. Can we identify and state clearly which of their properties are similar enough to justify their grouping together as PGMs?

Looks like a company has been formed, backed by multiple billionaires and a few hundred-millionaires to mine platinum group metals from extraterrestrial resources, in particular near-Earth asteroids. ( Mining Quarries Millions Of Miles From Earth, National Public Radio, 27 Apr 2012) If this were to work, we could see considerably different economics for platinum group metals after 2025–2035.

The parents, in this case, being Lutetium and Lawrencium in the periodic table. — Preceding unsigned comment added by 92.9.55.132 ( talk) 09:44, 4 April 2017 (UTC)

This is a poorly written article. The editors can't even distinguish between "than" and "then". I wonder if the editors even know that "groups 8, 9, and 10 are also referred to as Group VIIIB as well as Group VIII (yes, all of them together). Hint: these older designations explain WHY the 6 are called "platinum group". There is a 1996 usage table...almost 30 years old! That table has one use type as "autocatalysts". Uh, an autocatalyst is a chemical compound that catalyzes its own reaction, which is completely different from an internal combustion engine exhaust decomposition catalyst. The editors apparently believe that list all of the obsolete and exotic aliases is important. It is not. The FIRST thing the lead should do is NAME the 6 elements. Do they all occur elementally? IDK, but if they do that's important enough to mention up-front. Is their Periodic Table period and row important? I don't think so, but if it is, WHY it is ought to be explained. (That is, it is NOT important enough to be in the lead, imho.) It is absurd that the periodic table displayed shows neither the Period Numbers nor Row Numbers. There's half a dozen, at least, other issues I have with this but life's too short. 98.21.213.85 ( talk) 08:00, 28 November 2023 (UTC)
