Sphalerite is an important ore of zinc; around 95% of all primary zinc is extracted from sphalerite ore. [42] However, due to its variable trace element content, sphalerite is also an important source of several other metals such as cadmium, [ 43 ] gallium, [ 44 ] germanium, [ 45 ] and indium [ 46 ] which replace zinc.
English: Black tetrahedral crystals of sphalerite up to 8 mm in size across this matrix (4.5 × 3.0 × 2.0 cm) with chalcopyrite and calcite. Found from Creede, Mineral County, Colorado, USA. Found from Creede, Mineral County, Colorado, USA.
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 (although the cost of making each zinc penny is >1¢). The crystalline sphalerite specimen shown above is from the well-known Central Tennessee Zinc District (a.k.a ...
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 sulphide minerals are a class of minerals containing sulphide (S 2−) or disulphide (S 2− 2) as the major anion. Some sulfide minerals are economically important as metal ores . The sulphide class also includes the selenides , the tellurides , the arsenides , the antimonides , the bismuthinides, the sulpharsenides and the sulphosalts .
Pyrrhotite (pyrrhos in Greek meaning "flame-coloured") is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.125). It is a nonstoichiometric variant of FeS, the mineral known as troilite.
Since these ore deposits frequently form massive sulfide lenses, they are also named sediment-hosted massive sulfide (SHMS) deposits, [1] [4] as opposed to volcanic-hosted massive sulfide (VHMS) deposits. The sedimentary appearance of the thin laminations led to early interpretations that the deposits formed exclusively or mainly by exhalative ...
