What does sphalerite mean?
Sphalerite is a mineral form of zinc sulfide and the principal ore from which zinc is extracted. It usually occurs in crystals or masses associated with galena, pyrite, chalcopyrite, and other sulfide minerals. In appearance, it can resemble galena and was historically called zinc blende. The mineral has economic importance because it is the most important zinc ore, though its iron content can affect the quality of the metal produced. In geological studies, sphalerite is also examined for trace elements and fluid inclusions, which can provide information about the conditions under which the surrounding ore formed. Its name derives from a Greek word associated with deception, reflecting the historical difficulty of distinguishing it from superficially similar minerals.
nounSphalerite is a mineral composed primarily of zinc sulfide, with iron and other elements commonly present as impurities. It is the principal ore of zinc and is also known as zinc blende.
- A zinc sulfide mineral that is the principal ore of zinc.
"The mine produces sphalerite alongside galena and chalcopyrite."
"Sphalerite crystals were found throughout the fracture zone."
"The ore body contains sphalerite, galena, and pyrite."
Usually used in the plural when referring to multiple mineral specimens or deposits.
"The museum displays exceptional sphalerites from several mining districts."
Its name comes from a Greek word meaning “deceptive,” a reference to how easily sphalerite can be mistaken for other sulfide minerals.

Where does sphalerite come from?
The name sphalerite comes from the Greek sphaleros, meaning “deceptive” or “treacherous,” probably because sphalerite was easily mistaken for other ores with a similar metallic appearance. The mineral was also traditionally known as zinc blende, a name referring to its resemblance to lead-bearing galena while differing from it in composition. Its chemical identity as zinc sulfide was established more clearly during modern mineralogical analysis.
How sphalerite is actually used
Sphalerite is primarily used in geology, mining, and mineralogy. The alternative name zinc blende is common in older technical and mining literature.
Easily confused with sphalerite
Galena is a lead sulfide mineral and an ore of lead, whereas sphalerite is primarily zinc sulfide and is the chief ore of zinc.
