The new revolution of hydropower digitization
Hydropower is the world’s most mature and ancient renewable energy source, producing 1300 GW of power worldwide. It is a field in rapid evolution and with several emerging technologies. Among new trends Wolframite is an iron, manganese, and tungstate mineral with a chemical formula of (Fe,Mn)WO 4 that is the intermediate mineral between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic Wolframite

Skarn mineralogy and in-situ LA–ICP–MS U–Pb geochronology of wolframite for the Caojiaba tungsten deposit, southern China: Implications for a reduced tungsten skarn deposit.We present an analytical protocol for in situ U–Pb isotope dating of wolframite series minerals [(Fe,Mn)WO 4], the main ore mineral for tungsten, by LA-SF-ICP-MS. Precision and accuracy of the protocol was intensively assessed using our newly developed well-characterized U–Pb wolframite reference material.The tungsten oxide interference on Accurate and precise in situ U–Pb isotope dating of wolframite series

Compositional Variation in Wolframites from the Barroca Grande
Typical wolframite Nb 2 O 5 contents are below 1000 ppm, whilst values greater than 1000, 2000 and 4000 ppm are generally only found in wolframites less than 50, 30, and 10 metres respectively from major sub-vertical faults.Wolframite means "the devourer of tin" since the mineral interferes with the smelting of tin. — Source: "About Tungsten," from the series "It's Elemental," Jefferson Lab, a U.S. National laboratory located in Newport News, Virginia.
