Would be nice to add references to this in the popular culture, as I sometimes see on other pages. For example, the ore Pitchblende features prominently in the 1940 sci-fi move 'Dr. Cyclops'.
Could someone clarify the term 'massive' on the element table (next to pitchblende)? I'm familiar with pitchblende, but I can't understand the use of 'massive', is it just a weird name for Uraninite that happens to sound like an adjective? WLU 13:51, 19 March 2007 (UTC)
The (uranium oxide) mineral Uranite (U3O8) erroneously redirects here. I don't how to change that. Uranite does not currently have a page. It would be better if it redirected to Uranium Oxide. -- Morstar ( talk) 08:53, 11 March 2008 (UTC)
"Uranite" is not a valid mineral name but is an obsolete spelling of uraninite, UO2 (nor is U3O8 a mineral; i.e., U3O8 is not known to occur in Nature). 134.253.26.12 ( talk) 17:29, 16 September 2008 (UTC)
Will someone knowledgeable please describe how uranite is distributed in the earth? Does one find a vein of it and dig that? Does someone process a mountain of material to extract some? I'm sure there are industry terms that would make it clear where to look and how big a shovel to bring. —Preceding unsigned comment added by Fotoguzzi ( talk • contribs) 09:39, 7 January 2010 (UTC)
Uraninite is also really important for geology (especially determining past oxygen levels). I don't know very much about it, but if there is someone whose chemistry is stronger than mine could add a section on uraninite and geology, that would be really helpful.

The figure of 70 Bq/g seems very low for a decent ore, as pure uranium is more like 12 kBq/g. Should it be 70 kBq/g? I don't know where I would go for the true figure. — Preceding unsigned comment added by 92.40.174.209 ( talk) 06:40, 18 July 2013 (UTC)

Has pitchblende been analyzed extensively as to its stable elemental content? If the Curies were able to find the radioactive elements 84Po polonium and 92Ra Radium in it with an electroscope the question becomes as to whether there is possibly a stable isotope of either 84Po polonium (and specifically EE84Po210) or any other possibly stable residual radioactive decay product in the residual ore. WFPM ( talk) 22:19, 20 December 2012 (UTC)
It is interesting to note that it was the study of pitchblend by chemical decomposition that led the Curies to find and get credit for the discovery of the 2 elements 84OPo Polonium and 88Ra Radium by the use of a radiation detector (electroscope) and that nobody is noted as finding out definitely that there are no stable isotopes of these elements. It is noted in the Nubase data that the isotope EE84Po210 has the lowest mass excess value (-15953 kev) of any of the A = 210 Isotopes. And that is unusual since the lowest excess mass values of the other previous number isotopes in this atomic number area have either stable or else very long halflifed isotopes.

As is noted, the word 'blende' is an old miner's term for a mineral that's deceiving because of its appearance. The german verb 'blenden' means 'to dazzle' or 'to blind', but also 'to deceive'.
I would thus propose to change
from pitch, because of its black color, and blende, a term (otherwise meaning "shade" or "screen") used by German miners to denote minerals whose density suggested metal content, but whose exploitation, at the time they were named, was either unknown, impossible or not economically feasible).
to
from pitch, because of its black color, and blende, a term used by German miners to denote minerals whose density suggested metal content, but whose exploitation, at the time they were named, was either unknown or not economically feasible (from blenden meaning "to deceive").
Also trying to simplify the sentence a bit. Andy-the-chemist-87 ( talk) 12:53, 21 March 2019 (UTC)
