La sphalérite est le polytype ZnS-3 C stable dans les conditions ambiantes. Cubique, de groupe d'espace F 4 3m ( no 216 ), la structure de la sphalérite est basée sur un empilement cubique à faces centrées (cfc) de soufre, le zinc occupant la moitié des cavités tétraédriques ainsi formées (structure dite « blende »).

Commercially, sphalerite (Zn sulfide; CAS No. ) is the most important Zn ore, and Zn oxide (CAS No. ) is the most common Zn compound used in industry. From 2009 to 2013, the world production of Zn metal increased from 11,281,000 to 13,138,000 tonnes (International Lead Zinc Study Group, 2013 ).

A highly common mineral, but a few localities produce fine crystals including Germany, colorless crystals from Switzerland, the Czech Republic, Romania, transparent crystals from Spain, England, Canada, the USA, Mexico, and Peru. Sphalerite is pyroelectric, generates a charge when heated. It can fluoresce under ultraviolet light, particularly ...

Sphalerite also concentrates arsenic (0.01 weight %) and selenium (0.004 weight %). The almost monomineralic product results from buffering of sulfide concentrations at low values by sphalerite precipitation. These results show how microbes control metal concentrations in groundwater- and wetland-based remediation systems and suggest biological ...

The distribution of indium in sphalerite from hydrothermal veins in the Saint-Martinla-Sauveté district (Loire, France) was studied by microprobe. Several hundred analyses were carried out. Sphalerite, devoid of chalcopyrite inclusions, exhibits an oscillatory zoning which can be related to the variation of minor-element concentrations. Indium (up to 1.05 wt. %) is positively …
Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite …
The main problem associated with the oxidative leaching process of sphalerite is the slow dissolution rate in acidic ferric solution due to the formation of a passive layer on the sphalerite surface. This research examined the surface structure of the sphalerite concentrate, non-oxidized and oxidized in ferric sulfate solution using X-ray diffraction (XRD), Raman …
Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear to white crystals (known as Cleiophane ). Yellow to orange sphalerite is often called "golden sphalerite." Red shades of sphalerite are known as Ruby Blende or Ruby Jack. As iron content increases, sphalerite forms dark ...
with Cu(1I)-activated sphalerite, regardless of the activation time. The products formed on Pb(I1)-activated sphalerite depended on the activation times; a short activation time (30 min) yielded a lead ethylxanthate-like product, but a long activation time (90 min) yielded a considerable amount of dixanthogen.
The oxidation state and local atomic environment of admixtures of In, Cu, and Ag in synthetic sphalerite crystals were determined by X-ray absorption spectroscopy (XAS). The sphalerite crystals doped with In, Cu, Ag, In–Cu, and In–Ag were synthesized utilizing gas transport, salt flux, and dry synthesis techniques. Oxidation states of dopants …
Zinc is a bluish-white metallic element (symbol Zn; atomic no. 30) that is found in minerals such as franklinite, ghanite, goslarite, hemimorphite, smithsonite, sphalerite, willemite, and wurtzite. Sphalerite, which contains zinc sulfide, is the most abundant source. Zinc deficiency and toxicity have been reviewed [ 1, 2 ].

Sphalerite is an ore—a mineral of economic value—that was once mined in southeastern Kansas for its zinc content. It is also called zinc blende, blende, blackjack, and mock lead. Sphalerite crystals are usually shaped like triangular pyramids, with three sides and a base. Because it has good cleavage in six directions, sphalerite will break ...
sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore). The alternative …
