Manganotantalite Value, Price, and Jewelry Information
Manganotantalite makes a spectacular red brown gem that is a very rare collector’s item Transparent material is light enough in color to allow lots of light to enter and leave a cut gem, and properly cut stones are lively and brilliant Cutting is difficult because of the closely associated in nature and are the two most char one of the best accounts on the occurrence of Nb and Ta minerals is that given by Frommurze et al (1942) in the Explanation of Sheet No 79 (Karibib, SWA) contrast to manganotantalite which is often red to brownNIOBIUM AND TANTALUM MINERALSManganotantalite (Mn2+,Fe2+)(Ta,Nb)2O6 c 20012005 Mineral Data Publishing, version 1 Crystal Data: Orthorhombic Point Group: 2/m2/m2/m [Crystals short prismatic or equant, also tabular; in groups of parallel or subparallel crystals; massive] (by analogy toManganotantalite (Mn2+)(Ta 2 6 Handbook of MineralogyThe mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum It is chemically similar to columbite, and the two are often grouped together as a semisingular mineral called coltan or "columbitetantalite" in many mineral guides However, tantalite has a much greater specific gravity than columbite (80+ compared to columbite's 52) Ironrich tantalite is the mineral tantalite(Fe) or ferrotantalite and manganeserich is tantalite(Mn) or manganotantalite Tantalite WikipediaManganotantalite is a manganeserich variety of TantaliteIt is formed when manganese replaces iron Manganotantalite is an intense red transparent material that is Manganotantalite gemstone information

Mineral Mineral Occurrence and formation: Minerals form in all geologic environments and thus under a wide range of chemical and physical conditions, such as varying temperature and pressure The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process Manganese is a chemical element with the symbol Mn and atomic number 25 It is not found as a free element in nature; [not verified in body] it is often found in minerals in combination with ironManganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels First isolated in 1774, manganese is mainly used in the production of steelManganese WikipediaThe Rubies of Burma and Associated Minerals: Their Mode of Occurrence, Origin, and Metamorphoses A Contribution to the History of Corundum Barrington Brown, C; Judd, John W Abstract Publication: Philosophical Transactions of the Royal Society of London Series A Pub Date: 1896 DOI: 101098/rsta18960005 Bibcode: 1896RSPTA187151B The Rubies of Burma and Associated Minerals: Their Mode of Occurrence of Phlogopite in Carbonatite and Associated Alkaline Rocks at Beldih, Purulia District, West Bengal, India Melvin A Ekka1, Jugnu Prasad2 And D K Bhattacharya*3 1,2,3 University Department Of Geology, Ranchi University, Ranchi, Jharkhand ,India Corresponding Auther: Melvin A EkkaOccurrence of Phlogopite in Carbonatite and Associated 609 Thz Canadi an M inc ralo gist vol 36, pp 60963s (1998) OXIDE MINERALS OF THE SEPARATION RAPIDS RAREELEMENT GRANITIC PEGMATITE GROUB NORTHWESTERN ONTARIOOXIDE MINERALS OF THE SEPARATION RAPIDS RARE
