There are about 100 known cobalt-containing minerals, mainly including sulfur cobaltite (Co 3 S 4), fibrous pillar (CuCo 2 S 4), cobaltite (CoAsS), gray cobalt ore (CoAs 2), erythrite (3CoO·A S2 O 5 ·8H 2 O), etc. There are mainly four types of cobalt ores in the world. (1) Copper-cobalt ores, with the largest reserves in Congo (DRC) and Zambia.

Cobalt is relatively abundant in nature at around 10 to 30 parts per million. The common ores of cobalt include: cobaltite, smaltite, chloranthite, and linnaeite. The largest suppliers of cobalt are Zambia, Canada, Russia, Australia, Zaire, and Cuba. Cobalt it not currently mined in the United States.
In addition, a variety of designs and structures of cobaltite nanomaterials in different dimensions have been reported. These include 1D structures such as ZnCo 2 O 4 nanowires and internally hollow porous nanotubes (200–300 nm), which offer a large surface-to-volume ratio and superior electronic transport [68,74].Pendashteh et al. fabricated highly ordered mesoporous CuCo 2 O …
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.

cobalt (symbol Co) Metallic element, a transition metal, discovered c.1735.It is found in cobaltite and smaltite, but mostly obtained as a by-product during the processing of other ores. Cobalt is a constituent of vitamin B 12.It is used in high-temperature steel, artists' colours (cobalt blue), jet engine manufacture, cutting tools and magnets. Cobalt-60 (half-life 5.26yr) is …
The cobaltite perovskites LaCo1−xSnxO3 (x = 0.00, 0.03, 0.06, 0.09, and 0.12) were synthesized using the conventional sol–gel technique. The effect of Sn doping on the structural, magnetic, and dielectric properties of LaCoO3 has been studied. XRD and Rietveld's refinement revealed structural details of rhombohedral crystallized pure LaCoO3 compound. …

I have read in previous posts that cobaltite (Cobalt ore) isn't turned on by default and that we can reduce Cobalt Oxide from the advanced copper processing, however I cannot find the advanced copper processing nor can I find where I …
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 although rare is still an important and valuable ore of cobalt, a strategically and industrially useful metal. The symmetry of cobaltite is somewhat in dispute. Its structure is very similar to the structure of pyrite, FeS2. The sulfur to sulfur link (S-S) in pyrite is replaced by an arsenic to sulfur link (As-S) in cobaltite.
Cobalt forms a number of minerals: cobaltite [CoAsS], skutterudite [CoAs 3-x], erythrite [Co 3 (AsO 4) 2.8H 2 O], spherocobaltite [CoCO 3], and heterogenite [CoO(OH)]. It is widely distributed in igneous and sedimentary rocks and minerals. Cobalt is also present in meteorites (i.e., iron-nickel metal contains a few tenths of a percent cobalt).
Cobalt generally occurs as cobaltite, but other cobalt-bearing sulfarsenides and sulfide minerals have been described such as skutterudite, bravoite, safflorite, gersdorffite and …

Tom was thrilled and honored to be awarded both the Desautels Trophy for the "finest individual display of crystallized mineral specimens entered in the show" and the Lidstrom Trophy for "the outstanding single mineral specimen entered in the competition" at the 69th TGMS Show in 2024.
Due to its low concentration in ores, cobalt is usually considered to be a companion metal which is of limited economic interest. The bulk of global cobalt production emanates as a by-product of extraction of commodities such as copper (~55%), nickel (~35%), and arsenic (Azevedo et al., 2018, Smith, 2001).The only exceptions, which represent a small share of the …
