Joan Abella I Creus
Joan Abella i Creus (Sabadell, Barcelona, 1968) is a Catalan gemmologist and mineralogist who discovered abellaite, a mineral that receives this name in his honor Articles and publications In 2008 he published his first book, "Minerals i Mines de la conca minera de Bellmunt del Priorat", a unique work in the Catalan town of Bellmunt del Priorat, never before described. It consists of three parts: the first is a well-illustrated discussion of the history of mining in the area from the proto-Iberian era to the present. The second part describes most of the important Mine (industry), mines, as well as the methods of profit used. The third part is a description of the minerals that have been found there, accompanied by 100 photos of mineral samples from their own collection. He has also collaborated in the publication of several books, such as "Atlas de Asociaciones Minerales en láminas Prima" by Professor Joan Carles Melgarejo, "Minerales de España" by Joaquín Mollfulleda, "Miner ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Mineralogical Association
Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS). The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The next meeting is scheduled in 2022 in Lyon, France. Presidents The presidents of the IMA have been: * since 2021: Anhuai Lu ** Peking University *2018–2020: Patrick Cordier (born 1961) ** Université de Lille *2016–2018: Peter C.

Breithauptite
Breithauptite is a nickel antimonide mineral with the simple formula NiSb. Breithauptite is a metallic opaque copper-red mineral crystallizing in the hexagonal - dihexagonal dipyramidal crystal system. It is typically massive to reniform in habit, but is observed as tabular crystals. It has a Mohs hardness of 3.5 to 4 and a specific gravity of 8.23. It occurs in hydrothermal calcite veins associated with cobalt–nickel–silver ores. It was first described in 1840 from the Harz Mountains, Lower Saxony, Germany and in 1845 for occurrences in the Cobalt and Thunder Bay districts of Ontario, Canada. It was named to honor Saxon mineralogist Johann Friedrich August Breithaupt (1791–1873). See also *List of minerals *List of minerals named after people This is a list of minerals named after people.

Hopeite
Hopeite is a hydrated zinc phosphate with formula: Zn3(PO4)2·4H2O. It is a rare mineral used mainly as a collectors specimen. Hopeite crystallizes in the orthorhombic system with prism (geometry), prismatic, Glass, vitreous white to yellow crystals. It also forms Druse (geology), druzy encrustations and reniform (kidney-shaped) masses. The related mineral parahopeite, which has the same composition but different crystal structure, is triclinic. The minerals are formed through oxidation of sphalerite by the presence of phosphate-rich solutions It was first described in 1822 from Moresnet, Liège Province, Belgium and is named after Scottish people, Scottish chemist, Thomas Charles Hope (1766–1844) of the University of Edinburgh. It has been found in Zambia associated with lazulite. Hopeite is one of the 2 conversion minerals arising from the application of the rust converter 'Fertan'.
