the world's cobalt supply in 2014 was mined in the Democratic Republic of Congo. Mining and smelter activities in Katanga have contaminated soil, water and urban environments (Pourret et al. 2016). Cobalt forms a number of minerals: cobaltite [CoAsS], skutterudite [CoAs 3-x], erythrite [Co 3 (AsO 4) 2.8H2O], spherocobaltite [CoCO 3
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 has a metallic luster with a grayish black streak. It is brittle and fractures irregularly. ... Van Nostrand's Scientific Encyclopedia, Douglas M. Considine (ed ...
cobaltite, a cobalt sulfoarsenide mineral in which iron commonly replaces part of the cobalt [(Co,Fe)AsS], that occurs in high-temperature deposits. Notable occurrences are at Daşkäsän, in the lesser Caucasus, Azerbaijan; Tunaberg, Swed.; and Rājasthān, India.

Cobaltite is a sulfosalt mineral, containing sulfur, arsenic, and cobalt. It was discovered as early as 1832 from mines in the Cobalt district, Ontario, Canada. The mineral was named after the German word Kobold, which means "underground spirit" or "goblin", representing its elemental composition.
Natural copper ore is scarce, and its reserves have virtually been depleted. The copper minerals being mined industrially are copper sulfide and copper oxide. Copper sulfide minerals mainly include chalcopyrite, bornite, chalcocite, and covelline, among which chalcopyrite is the most common mineral.
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 …

When chunks of ore mined out of moons yield above-average densities of Cobaltite, the ore is called Copious Cobaltite and reprocessing returns approximately 15% higher quantities of useful material. A common ore commercially mined from moons, Cobaltite is very useful as it yields good quantities of Cobalt, a significant element of many …

Stabilization of As released upon recovering Co from the mineral cobaltite solves a long-standing environmental barrier to domestic cobalt mining. Potential to replace energy- and chemical-intensive industrial processes. Next step is to combine electrochemical dissolution of cobaltite with simultaneous scorodite formation. Hub …
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.

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.
Unlike other metals, cobalt is rarely found in its pure form. A small quantity is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). However, the vast majority comes from ore …

'Cobalt' published in 'Encyclopedia of Geochemistry' Cobalt is often associated with Ni, Ag, Pb, Cu, and Fe-Mn ores, from which it is most frequently obtained as a by-product (Gunn, 2014).The main known ore deposits are found in Katanga (Democratic Republic of Congo) (Decrée et al., 2015), whereas some recent discoveries …
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 steps, including locating suitable deposits and extracting the ore before refining it …
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 …
