en.wikipedia.org/wiki/FerritungstiteThe International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.. This list contains mineral synonyms, varieties and polytypes.

www.sciencedirect.com/science/article/pii/S0892687515301321The ferritungstite ore samples were treated by roasting with 25% Na 2 CO 3, 25% Na 2 SO 4 and 20% PAC under 800 °C for 60 min, followed by water leaching and magnetic separation. The phase evolution analysis results during roasting indicated that quartz and aluminum iron oxide transformed to sodium aluminum silicate and magnetite, while ...
www.mindat.org/min-27428.htmlThe recent crystallochemical data (Mills et al., 2016) was obtained basing on material ("elsmoreite", formerly known as "ferritungstite") from Hemerdon mine (now Drakelands mine) in Devon, UK. The 3C and 6R polytypes were recognized (see hydrokenoelsmoreite-3C and hydrokenoelsmoreite-6R).
