Cobaltite is a sulfide mineral composed of cobalt, arsenic, and sulfur, CoAsS. It naturally appears in the form of a tetartoid, a form of dodecahedron with chiral tetrahedral symmetry. Its impurities may contain up to 10% iron and variable amounts of nickel. Structurally, it resembles pyrite (FeS2) with one of the sulfur atoms replaced by an arsenic atom.
Cobaltite ores carved out of moons can occasionally yield very high densities of the valuable minerals. When this happens the ore is called Twinkling Cobaltite and reprocessing such ores will yield twice the normal volume of useful material. ... A common ore commercially mined from moons, Cobaltite is very useful as it yields good …
Cobaltite is a combined sulfur and arsenic salt of cobalt. It is mined in Canada (Ontario), Zaire, Azerbaijan, India (Rajasthan), England, Norway, and Sweden (Tunaberg). …

Cobaltite (CoAsS): Cobaltite is a sulfide mineral that typically occurs in hydrothermal veins associated with other sulfide minerals. It has a metallic luster and is usually opaque, with a silver-gray to white color. ... Cobalt ores are typically mined from cobalt deposits using various mining methods, such as open-pit mining, underground ...
Cobaltite - Encyclopedia. GEOGRAPHICAL NAMES: COBALTITE, a mineral with the composition CoAsS, cobalt sulpharsenide. It is found as granular to compact masses, and frequently as beautifully developed crystals, which have the same symmetry as the isomorphous mineral pyrites, being cubic with parallel hemihedrism. The usual forms are …
cobalt, Metallic chemical element, one of the transition elements, chemical symbol Co, atomic number 27. Widely dispersed in small amounts in many minerals and ores, this magnetic, silvery white metal with a faint bluish tinge is used mostly for special alloys (e.g., alnico, tool steel) with exacting applications.
Cobalt is recognised by the European Commission as a "Critical Raw Material" due to its irreplaceable functionality in many types of modern technology, combined with its current high-risk status associated with its supply. Despite such importance, there remain major knowledge gaps with regard to the geochemistry, mineralogy, and microbiology of …
Cobaltite was still being mined at Qamṣr in the 19th century: "Cobalt (ḵāk-e lājavarḍ . . . ) is found in considerable quantities near Kāšān in the village of Qamṣar. The mine is the property of a sayyed family. Significant amounts of cobalt ore are said to be exported to Russia" (Polak, II, p. 177).
Cobaltite is an important ore of the element cobalt. It forms very interesting and unusual crystals rarely seen in the mineral kingdom, especially the icosahedral type. The name of Cobaltite, and its namesake cobalt, is derived from the German equivalent of the …

Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines. The process of cobalt mining involves many …
Although rare it is mined as a significant source of the strategically important metal cobalt. Secondary weathering incrustations of erythrite, hydrated cobalt arsenate, are common.. The name is from the German, Kobold, "underground spirit" in allusion to the refusal of cobaltiferous ores to smelt properly. It occurs in high temperature hydrothermal deposits …

A common ore commercially mined from moons, Cobaltite is very useful as it yields good quantities of Cobalt, a significant element of many advanced materials.
Cobalt is not found as a free metal but is generally found in the form of ores.It is usually produced as a byproduct of nickel and copper mining activities. The main ores of cobalt are: cobaltite - cobalt arsenic sulfide (CoAsS); erythrite - hydrated cobalt arsenate (Co 3 (AsO 4) 2 •8H 2 O); glaucodot - cobalt, iron arsenic sulfide ((Co,Fe)AsS), in which the …
An ore is a mineral which has a valuable metal inside it. Ores are usually extracted by being mined.They can sometimes be found on the Earth's surface. Most ores are chemical compounds such as oxides or sulfides.There are different ways to get the metal out of the ore, which is called smelting. Iron ore, for example, is smelted in a blast furnace
The principal minerals are smaltite—a compound of cobalt and arsenic—and cobaltite—a compound of cobalt, arsenic, and sulfur. By the second decade of the 21st century, the Democratic Republic of the Congo, China, Canada, and Russia were the world's leading producers of mined cobalt. The largest producer of refined cobalt was China.
