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?
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.
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)
"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.
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)
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)
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)

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.

In the last sentence of the "Structure" section, it states:
The lead telluride mineral altaite has the same crystal structure as galena.
…with "Telluride" linking to the Telluride (chemistry) article. But should it instead link to the Telluride mineral article instead? – Lestatdelc ( talk) 01:04, 30 May 2024 (UTC)
