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 Target Addressed

Cobaltite is a sulfide mineral composed of cobalt, arsenic and sulfur, CoAsS. It contains up to 10 percent iron and variable amounts of nickel. Structurally it resembles pyrite (FeS2) with one of the sulfur atoms replaced by an arsenic atom. Although rare, it is mined as a significant source of the
Cobaltite is a mineral that contains cobalt and is often found alongside other ores such as nickel, silver, lead, copper, and iron. ...

For instance, approximately 1,800 tpa of Co is produced as a by-product of one of the largest known sulfide Ni ...
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 cobalt-bearing environments, …

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 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 …
Cobaltite symbolizes unlocking hidden potential. The name comes from the German word "Kobold," meaning a goblin-like creature. First found in Sweden, it was mined mainly for its cobalt. Sometimes called Cobalt Glance or Cobalt Pyrite, these names highlight its shiny, metallic look and similarity to other minerals.
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 and contact …
rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]). The elements cerium through lutetium are called the lanthanides, but many scientists also, though …
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
It is mined with nickel ores and the platinum values of the sperrylite are recovered in the ore processing and smelting operations. The mineral was discovered in 1889 by Francis Louis Sperry, an American chemist, in the nickel ores of Sudbury, Ontario. ...

COBALTITE . Cobaltite is an important cobalt ore mineral having the formula (Co,Fe)AsS - cobalt iron arsenic sulfide. It's essentially arsenopyrite with cobalt. Cobaltite has a metallic luster, a bright silvery color, a dark gray streak, and is moderately hard (H = 5.5). It can form cubic and pyritohedral crystals (the same crystal forms as ...
The main ores of cobalt are cobaltite, erythrite, glaucodot and skutterudite The Democratic Republic of the Congo currently produces 63% of the world's cobalt Cobalt is principally mined as a by-product of nickel and copper mining. Cobalt compounds have been used for centuries to impart a rich blue color to glass, glazes, and ceramics
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.
Compounds. In its compounds cobalt nearly always exhibits a +2 or +3 oxidation state, although states of +4, +1, 0, and −1 are known.The compounds in which cobalt exhibits the +2 oxidation state (Co 2+, the ion being stable in water) are called cobaltous, while those in which cobalt exhibits the +3 oxidation state (Co 3+) are called cobaltic.. Both Co 2+ and Co 3+ form …
