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 ...
Instead, indium is usually a trace constituent of more common ore minerals, such as sphalerite and chalcopyrite. [ 60 ] [ 61 ] From these, it can be extracted as a by-product during smelting. [ 19 ] While the enrichment of indium in these deposits is high relative to its crustal abundance, it is insufficient, at current prices, to support ...

The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix.
In Dutch, ë appears in the plural form of most words that end in -ie or -ee, like kolonie-> koloniën, zee-> zeeën, and knie-> knieën (Dutch-language rules stipulate an extra e before the ë in plurals if the accent falls on the syllable containing the ë).
