vanadinite

Other names that have since been given to vanadinite are johnstonite and lead vanadate.

Del Rio's lead mineral was later renamed vanadinite for its vanadium content.

Over 60 vanadium ores are known, including vanadinite, patronite, and carnotite.

Crystals of vanadinite conform to a hexagonal system of symmetry.

Del Río extracted the element from a sample of Mexican "brown lead" ore, later named vanadinite.

Some associated minerals include: calcite, galena, pyromorphite, smithsonite, vanadinite, and wulfenite.

The octahedron shares two of its opposite faces with that of neighbouring vanadinite units, forming a continuous chain of octahedrons.

Some noteworthy minerals from the Castle Dome Mountains region are vanadinite, wulfenite, barite, and fluorite.

A unit cell of vanadinite, the smallest divisible unit that possesses the same symmetry and properties, is in the form of a hexagonal prism.

Along with carnotite and roscoelite, vanadinite is one of the main industrial ores of the element vanadium, which can be extracted by roasting and smelting.

Touissit-Bou Beker is well-known among mineral collectors for fine specimens of Anglesite, cerussite, azurite, vanadinite and other minerals.

The region is known for striking combinations of cerussite, fluorite, vanadinite, wulfenite, barite, and mimetite, as well as galenite and anglesite.

Minor amounts of vanadium were produced from the Alderley Edge copper mine in Cheshire where the element occurs in vanadinite (Carlon, 1979).

It has been found in association with cerussite, descloizite, hemimorphite, hopeite, hydrozincite, "limonite", parahopeite, pyromorphite, scholzite, smithsonite, and vanadinite.

Vanadium was discovered by Andrés Manuel del Río, a Spanish-born Mexican mineralogist, in 1801 in the mineral vanadinite.

Del Río's "brown lead" was also rediscovered, in 1838 in Zimapan, Hidalgo, Mexico, and was named vanadinite because of its high vanadium content.

It occurs with cerussite, anglesite, smithsonite, hemimorphite, vanadinite, pyromorphite, mimetite, descloizite, plattnerite and various iron and manganese oxides.

The Hull Mine and Puzzler Mine in particular have produced atypical green vanadinite and mimetite as well as yellow-hued wulfenite.

Descloizite occurs in oxidised portions of veins of lead ores in association with pyromorphite, vanadinite, wulfenite, mottramite, mimetite and cerussite.

First discovered in 1801 in Mexico, vanadinite deposits have since been unearthed in South America, Europe, Africa, and in other parts of North America.

Each structural unit of vanadinite contains a chlorine ion surrounded by six divalent lead ions at the corners of a regular octahedron, with one of the lead ions provided by an adjoining vanadinite molecule.

Deposits of vanadinite are found worldwide including Austria, Spain, Scotland, the Ural Mountains, South Africa, Namibia, Morocco, Argentina, Mexico, and 4 states of the United States: Arizona, Colorado, New Mexico, and South Dakota.
