Aplowite
Aplowite is a very rare mineral with the formula CoSO4•4H2O, a naturally occurring cobalt(II) sulfate Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO4(H2O)x. Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO4.6H2O or CoSO4.7H2O, respectively. The heptahydrate is a red solid that is soluble in water and m ... tetrahydrate. It is the lower hydrate when compared to bieberite (heptahydrate) and moorhouseite (hexahydrate), and a higher hydrate when compared to cobaltkieserite (monohydrate).

Sulfate Minerals
The sulfate minerals are a class of minerals that include the sulfate ion () within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often included with the sulfates in mineral classification systems.Klein, Cornelis and Cornelius S. Hurlbut, 1985, ''Manual of Mineralogy,'' 20th ed., John Wiley and Sons, New York, pp. 347–354 . Sulfate minerals include: *Anhydrous sulfates ** Barite BaSO4 ** Celestite SrSO4 ** Anglesite PbSO4 ** Anhydrite CaSO4 ** Hanksite Na22K(SO4)9(CO3)2Cl *Hydroxide and hydrous sulfates ** Gypsum CaSO4·2H2O **Chalcanthite CuSO4·5H2O ** Kieserite MgSO4·H2O ** Starkeyite MgSO4·4H2O ** Hexahydrite MgSO4·6H2O ** Epsomite MgSO4·7H2O ** Meridianiite MgSO4·11H2O **Melanterite FeSO4·7H2O ** Antlerite Cu3SO4(OH)4 ** ...

Cobaltite
Cobaltite is an arsenide and sulfide mineral with the mineral formula Co As S. It is the naming mineral of the cobaltite group of minerals, whose members structurally resemble pyrite (FeS2). History Cobaltite was first described in 1797 by Klaproth.Page ''Cobaltite: Mineral information, data and localities'' on 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, often producing foul-smelling, poisonous fumes in the process. Properties Cobaltite 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.Klein, Cornelus and Cornrlius Hurlbut, 1996, ''Manual of Mineralogy'', 20th ed., Wiley, p.288, Cobaltite can be separa ...

Cobalt(II) Sulfate
Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO4(H2O)x. Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO4.6H2O or CoSO4.7H2O, respectively. The heptahydrate is a red solid that is soluble in water and methanol. Since cobalt(II) has an odd number of electrons, its salts are paramagnetic. Preparation, and structure It forms by the reaction of metallic cobalt, its oxide, hydroxide, or carbonate with aqueous sulfuric acid: : : The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively. : : : The hexahydrate is a metal aquo complex consisting of octahedral o(H2O)6sup>2+ ions associated with sulfate anions (see image in table). The monoclinic heptahydrate has also been characterized by X-ray crystallography. It also features o(H2O)6sup>2+ octahedra as well as one water of crystalliz ...

Bieberite
Bieberite (CoSO4 · 7H2O) is a pinkish red colored sulfate mineral high in cobalt content. The name is derived from the type locality at the copper deposit in Bieber, Hesse, Germany. It has been described and reported as far back as the 1700s.Sage (1791) ''Le Journal de physique et le radium, Paris'', 39: 53 (as Cobalt Vitriol).Klaproth, M.H. (1797) "''Untersuchung des natürlichen Kobaltvitriols von Herrengrund, Beiträge zur chemischen Kenntniss der Mineralkörper"'', Zweiter Band, Rottmann Berlin, pp. 320.Kopp (1808) ''Allgemeines Journal der Chemie, Berlin 1798-1803 (Scherer’s Journal)'', 6: 157 (as Kobaltvitriol).Beudant, F.S.

Moorhouseite
Moorhouseite is a rare mineral with the formula CoSO4•6H2O, a naturally occurring cobalt(II) sulfate hexahydrate. It is the lower-hydrate-equivalent of bieberite (heptahydrate) and aplowite (hexahydrate). It is also hydrated equivalent of cobaltkieserite. It occurs together with moorhouseite within efflorescences found in the Magnet Cove Barium Corporation mine in Walton, Nova Scotia, Canada.

Cobalt Minerals
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. 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 language, German for ''goblin ore'') for some of the blue pigment-producing minerals. They were so named because they were poor in known metals and gave off poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), which was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoclinic Minerals
In crystallography, the monoclinic crystal system is one of the seven crystal systems. A crystal system is described by three Vector (geometric), vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a parallelogram prism (geometry), prism. Hence two pairs of vectors are perpendicular (meet at right angles), while the third pair makes an angle other than 90°. Bravais lattices Two monoclinic Bravais lattices exist: the primitive monoclinic and the base-centered monoclinic. For the base-centered monoclinic lattice, the primitive cell has the shape of an oblique rhombic prism;See , row mC, column Primitive, where the cell parameters are given as a1 = a2, α = β it can be constructed because the two-dimensional centered rectangular base layer can also be described with primitive rhombic axes. The length a of the primitive cell below equals \frac \sqrt of the conventional cell above. Crystal class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minerals In Space Group 14
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases. ...
