Zinkenite is a steel-gray metallic sulfosalt mineral composed of lead antimony sulfide Pb 9 Sb 22 S 42.Zinkenite occurs as acicular needle-like crystals. [2]It was first described in 1826 for an occurrence in the Harz Mountains, Saxony-Anhalt, Germany and named after its discoverer, German mineralogist and mining geologist, Johann Karl Ludwig Zinken (1790–1862).
Zincite is the mineral form of zinc oxide (Zn O).Its crystal form is rare in nature; a notable exception to this is at the Franklin and Sterling Hill Mines in New Jersey, an area also famed for its many fluorescent minerals.
Andorite is a sulfosalt mineral with the chemical formula PbAgSb 3 S 6.. It was first described in 1892 for an occurrence in the Baia Sprie mine, Baia Sprie, in what is now Maramureș County, Romania, and named for Hungarian amateur mineralogist Andor von Semsey (1833–1923).
Franckeite, chemical formula Pb 5 Sn 3 Sb 2 S 14, belongs to a family of complex sulfide minerals.Franckeite is a sulfosalt.It is closely related to cylindrite.. It was first described in 1893 for an occurrence in Chocaya, Potosí Department, Bolivia.
Boulangerite or antimonbleiblende is an uncommon monoclinic orthorhombic sulfosalt mineral, lead antimony sulfide, formula Pb 5 Sb 4 S 11. [2] It was named in 1837 in honor of French mining engineer Charles Boulanger (1810–1849), [3] and had been a valid species since pre-IMA.
Zinkgruvan, a zinc mine in Askersund Municipality, Sweden. Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc minerals in ore as its primary product.
In the naming of inorganic compounds, "-zincate" is a suffix that indicates that a polyatomic anion contains a central zinc atom. Examples include tetrachlorozincate, ZnCl 4 2−, the tetrahydroxozincate, Zn(OH) 4 2− and tetranitratozincate, Zn(NO 3) 4 2−.
