Sphalerite is a sulfide mineral with the chemical formula (Zn, Fe)S. [5] It is the most important ore of zinc . Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative , Mississippi-Valley type , and volcanogenic massive sulfide deposits.
Sphalerite is also distinctive in being moderately heavy for its size and having six different planes of cleavage. 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 ...
Chemically, it is cadmium sulfide, and occurs as a bright yellow coating on sphalerite or siderite in vugs, deposited by meteoric water. [ 4 ] It was discovered in 1955 in the Hector-Calumet mine, Keno-Galena Hill area, Yukon Territory and named in honour of mineralogist James Edwin Hawley (1897–1965), a professor at Queen's University in ...

Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2] It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite ...
The enterprise known as Trepça was a conglomerate of 40 mines and factories, located mostly in Kosovo but also in locations in Montenegro.But the heart of its operations, and the source of most of its raw material, is the vast mining complex to the east of Mitrovica in the north of Kosovo, famous since Roman times.
The Albanians (Albanian: Shqiptarët) and their country Albania (Shqipëria) have been identified by many ethnonyms.The native endonym is Shqiptar.The name "Albanians" (Latin: Albanenses/Arbanenses) was used in medieval Greek and Latin documents that gradually entered European languages from which other similar derivative names emerged.
