 * This material's crystal structure happens to be the prototype for all commercial compound semiconductors. I might eventually want to calve off the zincblende and zinc blende redirect pages into an article on general properties of this crystal structure, with a navigational aid at the top linking to this mineralogy page.  Otherwise, lots of materials scientists might come traipsing through here looking for info on GaAs, AlGaAs, InGaP, ...--Joel 00:00, 17 May 2005 (UTC)


 * The lustre of sphalerite is submetallic, rather than resinous as was previously stated in the article. It is listed in the submetalic lustre category. --turkeybrain 02:54, 21 August 2008 (UTC)


 * Most refs (Webmineral, Mindat) state adamantine to resinous (esp. for low iron), but high Fe varieties verge on submetallic (Dana's Manual). Vsmith (talk) 03:31, 21 August 2008 (UTC)


 * Shouldn't we add some basic chemical data such as melting point, solubility in water etc.? —Preceding unsigned comment added by 194.53.253.51 (talk) 14:51, 18 November 2009 (UTC)


 * Second that, especially since I'm told that sphalerite has no melting point, subliming at 1185 C. This seems like a pretty interesting property to me. 98.221.97.100 (talk) 19:15, 27 December 2010 (UTC)

See zinc sulfide. Sphalerite is mostly ZnS, but impurities/other phases (whose presence is common for most minerals) would change its properties, such as melting. Perhaps this is a reason why they are not listed in the mineral articles. Materialscientist (talk) 00:01, 28 December 2010 (UTC)

Uses of Sphalerite
I have added a "Uses" heading for sphalerite but it requires more information and is a major gap in the article that needs to be filled in. Laurenmacky (talk) 01:34, 18 March 2021 (UTC)

Reorganization of sections
I have changed the "chemistry" heading to "crystal habit and structure", and then added a new heading on "properties"; the information from the original chemistry heading has been split into these new ones. Additionally, I have merged the "economic importance" and "gemstone" headings under a new one titled "uses" because there was not enough information in them to remain separate. There is a gap in information about how sphalerite is mined and turned into zinc that should be added as a new section.Laurenmacky (talk) 01:38, 18 March 2021 (UTC)

Strange contradiction with German version of article
This article says that "German geologist Ernst Friedrich Glocker discovered sphalerite in 1847, naming it based on the Greek word sphaleros, meaning "deceiving", due to the difficulty of identifying the mineral." - By contrast, the German langugage version of this article claims that the ore was understood to be a Zink ore in 1735 and that the name stuck around from before when it was already know but thought to be a misleading lookalike. Both claims are sourced. I have no clue which one is correct, but maybe someone else does and can look into this. — Preceding unsigned comment added by 2A01:C22:D152:6A00:294C:4CF2:FE53:9B82 (talk) 15:31, 22 September 2023 (UTC)
