Cobaltite was first described in 1797 by Klaproth. [6] Its name stems from the contained element cobalt, whose name is attributed to the German term Kobold, referring to an "underground spirit" or "goblin". The notion of "bewitched" minerals stems from cobaltite and other cobalt ores withstanding the smelting methods of the medieval period ...
Lithium cobalt oxide, sometimes called lithium cobaltate [2] or lithium cobaltite, [3] is a chemical compound with formula LiCoO 2 . The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide .
Associated minerals are arsenopyrite, native silver, erythrite, annabergite, nickeline, cobaltite, silver sulfosalts, native bismuth, calcite, siderite, barite and quartz. [3] It is mined as an ore of cobalt and nickel with a by-product of arsenic.
Cobalt-based blue pigments (cobalt blue) have been used since antiquity for jewelry and paints, and to impart a distinctive blue tint to glass. The color was long thought to be due to the metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue pigment-producing minerals.
Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements.. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [1]
If hydrochloric acid is used then cobalt may be extracted using alamine 336 in meta-xylene. [4] Cobalt can be extracted also using dialkylphosphinic acid. When cobalt carbonate (CoCO 3) is heated (calcined) above 400 °C it decomposes into carbon dioxide (CO 2) and cobalt(II) oxide (CoO) and can be refined as an oxide concentrate (see above).
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
