(~8.5 centimetres (3.3 in) across at its widest)\n\u003C\u002Fp>\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are about 5400 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Sphalerite is a somewhat common zinc sulfide mineral (ZnS).  It has a metallic to submetallic to resinous to adamantine luster.  Many metals can substitute for the zinc, such as iron, cadmium, and manganese.  Sphalerite almost always has some iron in it, so a better chemical formula would be (Zn,Fe)S.  Sphalerite has a wide color range, depending principally on iron content.  Pure to almost pure sphalerite is whitish to greenish.  With increasing iron content, sphalerite becomes yellowish to brownish to blackish.  One variety of sphalerite has a strikingly intense dark red color (ruby sphalerite).  It's streak color also varies with iron content from whitish to pale yellowish to brownish.  Sphalerite is also distinctive in being moderately heavy for its size and having six different planes of cleavage.\n\u003C\u002Fp>\u003Cp>Sphalerite is the most important zinc ore mineral.  Zinc produced from sphalerite is used for many purposes, including mixing with copper to produce brass, rust protection of iron & steel, and for making modern American pennies (although the cost of making each zinc penny is >1¢).\n\u003C\u002Fp>\u003Cp>The crystalline sphalerite specimen shown above is from the well-known Central Tennessee Zinc District (a.k.a. Central Tennessee Ba-F-Pb-Zn District).  In this mining district, sphalerite mineralization is hosted in shallow marine dolostones of the upper Knox Group (Lower Ordovician) - probably from dissolution collapse brecciated and karstified dolomitized limestones of the Mascot Dolomite.  The Central Tennessee Zinc District is a Mississippi Valley-type deposit in the Nashville Dome.  It formed by mineralization from heavy metal-rich basinal brines that migrated from the adjacent Illinois Basin or Appalachian Basin.  Published research indicates that mineralization occurred during the Late Paleozoic (Mississippian to Permian) and was associated with the Allegheny Orogeny, a tectonic collision event between Africa and North America.  Main stage calcite in the Central Tennessee Mining District dates to 260±42 Ma (= Late Permian).\n\u003C\u002Fp>\u003Cp>Locality: attributed to a mine near the town of Carthage, Smith County, north-central Tennessee, USA\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of sphalerite:\n\u003C\u002Fp>\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3727\">http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3727\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fgallery.php?min=3727<\u002Fa>","James St. John",3063,2685,{"id":871,"source_url":872,"license_code":873,"credit_html":874,"title":875,"description":876,"author":877,"original_width":878,"original_height":879},66201,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=109262344","CC BY-SA 2.0","Jan Helebrant, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=109262344\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","IMGP2024888 (51400971874).jpg","\u003Cp>milky quartz - SiO2 (+ sphalerite ZnS)\nlocality: Stříbro, Czech Republic\nphoto (c) 2021 Jan Helebrant\n\u003C\u002Fp>\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"http:\u002F\u002Fwww.juhele.blogspot.com\">http:\u002F\u002Fwww.juhele.blogspot.com\u003C\u002Fa>\" rel=\"noreferrer nofollow\">www.juhele.blogspot.com<\u002Fa>","Jan Helebrant",4000,3000,{"id":881,"source_url":882,"license_code":883,"credit_html":884,"title":885,"description":886,"author":887,"original_width":888,"original_height":889},66202,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=113716220","CC BY-SA 4.0","Koreller, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=113716220\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Muséum de Nantes - 009 - Sphalérite (Pologne).jpg","Sphalérite, en provenance de Pologne, au Muséum de Nantes","Koreller",4272,2848,{"id":891,"source_url":892,"license_code":883,"credit_html":893,"title":894,"description":895,"author":887,"original_width":896,"original_height":897},66205,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=113749619","Koreller, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=113749619\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Muséum de Nantes - 527 - Sphalérite (Saint-Laurent-du-Minier, France).jpg","Sphalérite, en provenance de Saint-Laurent-du-Minier (France), au Muséum de Nantes",3220,2440,{"id":899,"source_url":900,"license_code":901,"credit_html":902,"title":903,"description":904,"author":905,"original_width":906,"original_height":907},66208,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=167119249","CC BY 4.0","Animalculum, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=167119249\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Sphalerite 2, Musee de Mineralogie, Paris, 2025.jpg","Sphalerite from Dalnegorsk, Russia in Musee de Mineralogie, Paris","Animalculum",3072,2304,{"id":909,"source_url":910,"license_code":883,"credit_html":911,"title":912,"description":913,"author":914,"original_width":915,"original_height":916},66209,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=180416036","Марися Лебідь, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=180416036\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Сфалерит (брункіт).jpg","Minerals in the Mineralogical Museum of Lviv","Марися Лебідь",4080,3060,{"id":918,"source_url":919,"license_code":920,"credit_html":921,"title":922,"description":923,"author":924,"original_width":925,"original_height":926},66210,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=186707096","CC0 1.0","Gompit, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=186707096\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Sphalerite from Broken Hill.jpg","Sphalerite in Blue Quartz from Broken Hill, Australia","Gompit",3264,2448,{"id":928,"source_url":929,"license_code":853,"credit_html":930,"title":931,"description":932,"author":933,"original_width":934,"original_height":935},49489,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10029956","Robert M.

(CSM 54019, Colorado School of Mines Geology Museum, Golden, Colorado, USA)\n\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5500 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Chalcopyrite is a copper iron sulfide mineral (CuFeS2).  Many pyrite-like minerals exist, such as pyrite, marcasite, arsenopyrite, pyrrhotite, and chalcopyrite.  Chalcopyrite has a metallic luster, a deep yellowish-brassy color, a dark gray streak, a hardness of about 3.5 to 4, and no cleavage.  Many specimens have a multicolored iridescent tarnish, which can be artificially produced by exposure to certain chemicals (often acid).

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5500 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Chalcopyrite is a copper iron sulfide mineral (CuFeS2).  Many pyrite-like minerals exist, such as pyrite, marcasite, arsenopyrite, pyrrhotite, and chalcopyrite.  Chalcopyrite has a metallic luster, a deep yellowish-brassy color, a dark gray streak, a hardness of about 3.5 to 4, and no cleavage.  Many specimens have a multicolored iridescent tarnish, which can be artificially produced by exposure to certain chemicals (often acid).

name sphalerite carries a small joke about miners' frustration. Dark varieties looked so much like galena, the lead ore, that miners would dig them up only to find no lead[1]. The German word for it was *blende* — from *blind* or *deceiving* — long before any scholar wrote it down[2].\n\nBetween the 7th and 16th century CE, smiths used the zinc in sphalerite to make brass[3]. They heated the ore alongside copper to produce an alloy of copper with 3 to 45 percent zinc, before zinc itself was understood as a distinct element.\n\nGeorgius Agricola formalised *blende* in print in 1546[4]. Various chemical-based names followed over the next three centuries, including *zincum*[5]. Vernacular names piled up too: *zinc blende*, *black-jack*, *ruby blende*[6].\n\nIn 1847, the German mineralogist Ernst Friedrich Glocker drew the modern scientific name from the Greek *sphaleros*, meaning *treacherous*[7].","claude-opus-4-7","1.7.0","2026-06-01 15:27:36",{"markdown":1765,"model_version":1761,"prompt_version":1762,"reviewed_at":1766},"Roughly 95 percent of the world's primary zinc starts as sphalerite[1]. The mineral is the chief ore of zinc — the source from which everything downstream is made[2].\n\nMost of that zinc ends up coating other metals against corrosion. Galvanising layers it onto steel, giving sheet metal and structural shapes their rust-resistant surface[3]. Smaller shares go into brass and into dry-cell batteries[4].\n\nSphalerite is also the principal source of several quieter metals. Cadmium, gallium, germanium, and indium substitute for zinc in the crystal lattice and are recovered as by-products of zinc refining[5].","2026-06-01 15:29:10"]
