Zinc

ZnZn 2+ zinc alloy
Sphalerite ((Zn, Fe)S) is a mineral that is the chief ore of zinc.
The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral.

Zinc sulfide

ZnSzinc sulphideglow-in-the-dark
It consists largely of zinc sulfide in crystalline form but almost always contains variable iron.
This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite.

Galena

argentiferous galenagalenitelead
It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite.
It is often associated with the minerals sphalerite, calcite and fluorite.

Sulfur

Sphalerite ((Zn, Fe)S) is a mineral that is the chief ore of zinc.
Common naturally occurring sulfur compounds include the sulfide minerals, such as pyrite (iron sulfide), cinnabar (mercury sulfide), galena (lead sulfide), sphalerite (zinc sulfide), and stibnite (antimony sulfide); and the sulfate minerals, such as gypsum (calcium sulfate), alunite (potassium aluminium sulfate), and barite (barium sulfate).

Mineral

mineralsmineral depositsaccessory mineral
Sphalerite ((Zn, Fe)S) is a mineral that is the chief ore of zinc. It has a yellow or light brown streak, a Mohs hardness of 3.5–4, and a specific gravity of 3.9–4.1.
Examples are cinnabar (HgS), an ore of mercury, sphalerite (ZnS), an ore of zinc, or cassiterite (SnO 2 ), an ore of tin.

Wurtzite

The hexagonal analog is known as the wurtzite structure.
Wurtzite is a zinc iron sulfide mineral ((Zn,Fe)S) a less frequently encountered mineral form of sphalerite.

Fluorite

fluorsparBlue Johnfluorospar
It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite.
It may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite.

Cleavage (crystal)

Sphalerite crystallizes in the isometric crystal system and possesses perfect dodecahedral cleavage.

Fluorescence

Some specimens are also fluorescent in ultraviolet light.
Low-iron sphalerite (zinc sulfide), fluoresces and phosphoresces in a range of colors, influenced by the presence of various trace impurities.

Like other minerals with a cubic crystal structure, sphalerite may show a tetrahedral crystal habit.

Neudorf im Harz was known its mining and the mineral specimens of great beauty that were discovered here and which had become much sought after collectors' items by the 19th century (including specimens containing galenite, siderite, quartz, zinc blend and bournonite crystals).

Germanium

However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium, gallium germanium, and indium.
Today, germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores.

Sulfide minerals

Alston Moor

Alston Moor had some of the largest deposits of lead and zinc ores in Britain.

Cadmium

However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium, gallium germanium, and indium.
The only cadmium mineral of importance, greenockite (CdS), is nearly always associated with sphalerite (ZnS).

Dispersion (optics)

Crystals of suitable size and transparency have been fashioned into gemstones, usually featuring the brilliant cut to best display sphalerite's high dispersion of 0.156 (B-G interval), over three times that of diamond.

However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium, gallium germanium, and indium.
They dissolved the minerals pyrite, arsenopyrite, galena and sphalerite in hydrochloric acid and distilled raw zinc chloride.

Cubic crystal system

Sphalerite crystallizes in the isometric crystal system and possesses perfect dodecahedral cleavage. The mineral crystallizes in the cubic crystal system.
The Zincblende structure (also written "zinc blende") is named after the mineral zincblende (sphalerite), one form of zinc sulfide (β-ZnS).

Gallium

However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium, gallium germanium, and indium.
Gallium was discovered using spectroscopy by French chemist Paul Emile Lecoq de Boisbaudran in 1875 from its characteristic spectrum (two violet lines) in a sample of sphalerite.

Lustre (mineralogy)

Its luster is adamantine, resinous to submetallic for high iron varieties.
A submetallic lustre often occurs in near-opaque minerals with very high refractive indices, such as sphalerite, cinnabar, anthracite, and cuprite.
