Curite
} Curite is a rare mineral with the chemical composition Pb3 UO2)4O4(OH)3sub>2·2 H2O. It is therefore a hydrated lead uranyl oxide, which forms red needles or orange, massive aggregates. Etymology and history Curite was first found at Shinkolobwe mine (formerly known as "Kasolo mine“) in Katanga Province in the Democratic Republic of the Congo. Alfred Schoep (1881–1966) described the mineral for the first time in 1921 and named it after physicist and Nobel laureate Pierre Curie (1859–1906). Classification The mineral is classified according to Strunz as part of the uranyl hydroxides, forming its own group with additional cations (K, Ca, Ba, Pb etc.) and primarily UO2(O,OH)5 pentagonal polyhedra with system number 4.GB.55. Dana classifies the mineral to the oxides and hydroxide, as part of the uranium- and thorium-containing oxides with oxidation state +6 containing Pb, Bi, hydroxyl groups or water. Crystal structure Curite crystallizes orthorhombically in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shinkolobwe
Shinkolobwe, or Kasolo, or Chinkolobew, or Shainkolobwe, was a radium and uranium mine in the Haut-Katanga Province of the Democratic Republic of the Congo (DRC), located west of Likasi (formerly Jadotville), south of Kambove, and about northwest of Lubumbashi. The mine produced the most economical uranium ore in the world and was used for the Manhattan Project and subsequent Nuclear weapons of the United States, nuclear weapons produced by the United States in the 1940s and 50s. Before World War II, uranium extracted here was originally taken to Belgium to be processed; this supply was captured by the Wehrmacht in 1940 and subsequently used for the unsuccessful German nuclear program. The Shinkolobwe mine was officially closed in 2004. Toponym The mine's name was taken from the long-gone nearby village of Shinkolobwe. It is also slang for "a man who is easygoing on the surface but who becomes angry when provoked". Geology The mineral deposits at Shinkolobwe were discove ...

Kasolite
Kasolite is an uncommon lead uranyl silicate monohydrate mineral. It is an IMA approved mineral, that had been a valid species before the foundation of the association, that had been first described and published in 1921 by Schoep. It is a grandfathered mineral, meaning the name kasolite is still believed to refer to a valid species to this day. The mineral's name originates from its type locality, namely the Shinkolobwe Mine, also known as Kasolo Mine. Kasolite is possibly the lead analogue of the unnamed phase UM1956-02-SiO:CaHU, and it is the only accepted lead-uranium silicate. Visual properties Kasolite occurs in prismatic, lath-like crystals. It typically forms either clusters of radial acicular crystals, microcrystals, or a coating on top of the altered specimens. Individual crystals can grow up to a few millimeters. Massive specimens tend to have a dull to earthy luster. Kasolite is a weakly pleochroic mineral, which is an optical phenomenon. The mineral's color seems ...

Soddyite
Soddyite is a mineral of uranium. It has yellow crystals and usually mixed with curite in oxidized uranium ores. It is named after the British radiochemist and physicist Frederick Soddy (1877–1956). Soddyite has been a valid species since 1922, following its discovery in the locality of the Shinkolobwe uranium mine in the Haut-Katanga Province of the Democratic Republic of the Congo The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo (the last ambiguously also referring to the neighbouring Republic of the Congo), is a country in Central Africa.

Rutherfordine
Rutherfordine is a mineral containing almost pure uranyl carbonate ( U O2 CO3). It crystallizes in the orthorhombic system in translucent lathlike, elongated, commonly radiating in fibrous, and in pulverulent, earthy to very fine-grained dense masses. It has a specific gravity of 5.7 and exhibits two directions of cleavage. It appears as brownish, brownish yellow, white, light brown orange, or light yellow fluorescent encrustations. It is also known as ''diderichite.'' It was first described in 1906 for an occurrence in the Morogoro Region of Tanzania. It was named for Ernest Rutherford. It has been reported in the Democratic Republic of Congo, the Northern Territory of Australia and a variety of locations worldwide. It occurs as a secondary mineral as a weathering product of uraninite. In addition to uraninite it occurs associated with the rare minerals becquerelite, masuyite, schoepite, kasolite, curite, boltwoodite, vandendriesscheite, billietite, metatorbernit ...

Oxide Mineral
The oxide mineral class includes those minerals in which the oxide anion (O2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class. Minerals with complex anion groups such as the silicates, sulfates, carbonates and phosphates are classed separately.

Torbernite
Torbernite, also known as chalcolite, is a relatively common mineral with the chemical formula Cu UO2)(PO4)sub>2(H2O)12. It is a radioactive, hydrated green copper uranyl phosphate, found in granites and other uranium-bearing deposits as a secondary mineral. The chemical formula of torbernite is similar to that of autunite in which a Cu2+ cation replaces a Ca2+ cation. Torbernite tends to dehydrate to metatorbernite with the sum formula Cu UO2)(PO4)sub>2(H2O)8. Etymology and history Torbernite was found for the first time at Georg Wagsfort Mine near Johanngeorgenstadt in the Ore Mountains in Saxony. It was first mentioned in 1772 by Ignaz von Born in his work ''Lythophylacium Bornianum'', calling it "mica viridis crystallina, ibid." (green crystalline mica from Johanngeorgenstadt, Sax.; ''ibid.'' = "as the item above"). In 1780 Abraham Gottlob Werner uses Born's work and describes the mineral in more detail, calling it at first "grüner Glimmer" (green mica), later ...

Schoepite
Schoepite, empirical formula (UO2)8O2(OH)12·12(H2O) is a rare alteration product of uraninite in hydrothermal uranium deposits. It may also form directly from ianthinite. The mineral presents as a transparent to translucent yellow, lemon yellow, brownish yellow, or amber orthorhombic tabular crystals. Although over 20 other crystal forms have been noted; rarely in microcrystalline aggregates. When exposed to air schoepite converts over a short time to the metaschoepite form (UO3·H2O, ) within a few months of being exposed to ambient air. The hardness is 2.5, density is 4.8 g/cm3, and it streaks yellow. It was first described from specimens from Shinkolobwe mine in Belgian Congo in 1923, several additional localities are known. Schoepite was named to honor Alfred Schoep (1881–1966), Professor of Mineralogy at the University of Ghent, Belgium Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe.
