Note[edit]

what are the uses for this mineral?

why does it list "also used for healing"? what the heck are they talking about? should that be deleted?

Should this be merged with Lead sulphide?[edit]

Lead sulphidedoesn't seem to say anything about Galena but since Lead Sulfide is just the new spelling of Lead Sulphide they must be the same thing. So should they be merged? I don't know how to merge articles btw.

No, galena is the mineral form of the chemical lead sulfide. This is a mineral article whereas lead sulfide is about the chemical uses of the chemical lead sulfide. Lead sulfide is the correct IUPAC spelling and is the spelling used in chemical and science articles on Wikipedia. -Vsmith 22:21, 22 Apr 2005 (UTC)

No to merge, again[edit]

This article is about the mineral galena - the major ore of lead. It is not about the chemical lead sulfide. It does need to be expanded with more geologic and mineralogic info. Vsmith 12:10, 13 May 2005 (UTC)[reply]

I'm the guy that did the latest merge request. You're the geology person, so I'll go along with your strategy. Since we agree the article needs expansion, I'm going to label it a stub. I'm also going to revise the link to lead sulfide in a way that indices that Galena and lead sulfide are just two names for the same thing. If you think I'm overstating the case, feel free to revise my text, but if you do so, you should describe exactly how Galena rocks lying on the ground differ from lead sulfide on the laboratory shelf.---Isaac R 16:12, 13 May 2005 (UTC)[reply]

Need Source or Deleate[edit]

"In ancient Israel it was used to colour eyes blue.[citation needed]" Am I to undestand that they actually colored there eyes blue with this mineral. It seems far more likey it was used as a cosmedic in some way on eyelids in some way.

Picture is wrong[edit]

The picture of galena's "unit cell" is very wrong. This picture shows a structure of 13 molecules, whereas the unit cell of galena only has 4 molecules. The picture shown here is a representation of the cubic close-packed structure of galena with all octahedral sites filled, or, in other words, a propagation of the unit cell 3+ times. —Preceding unsigned comment added by 128.84.145.68 (talk) 20:06, 14 October 2007 (UTC)[reply]

Toxic?[edit]

Is galena toxic? can children safely handle it? Seems like the article should mention this. It is not enough to know that lead sulfide is toxic because this is the mineral article. —Preceding unsigned comment added by 74.68.152.245 (talk) 21:22, 9 January 2009 (UTC)[reply]

It is exactly as toxic as the appropriate kind of lead sulfide, which is described in some detail in that article. — Preceding unsigned comment added by Victor Engel (talk • contribs) 16:13, 2 August 2012 (UTC)[reply]

Density vs. Specific Gravity[edit]

This article and the lead sulfide article are inconsistent in referring to this quantity. Is there some reason for the inconsistency? Victor Engel (talk) 16:12, 2 August 2012 (UTC)[reply]

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). In addition to lead, some deposits contain up to 0.5 percent silver, in the form of silver sulfide or as limited silver in solid solution; when present, this byproduct far surpasses the main lead ore in revenue. Galena has been used since antiquity, one of its oldest uses being the production of kohl, an eye cosmetic now regarded as toxic due to the risk of lead poisoning. In modern times, galena is primarily used to extract its constituent minerals. In addition to silver, it is the most important global source of lead, for uses such as in lead-acid batteries. This sample of galena, measuring 3.5 cm × 2.5 cm × 2.0 cm (1.38 in × 0.98 in × 0.79 in), contains a small amount of gold-colored pyrite and was extracted from the Huanzala Mine in the Peruvian region of Ancash. This photograph was focus-stacked from 156 separate images.
