Minerals of the Eudialyte Group from the Sagasen Larvikite Quarry, Porsgrunn, Norway
= Minerals of the eudialyte group from the Sagasen larvikite quarry, Porsgrunn, Norway Alf Olav Larsen, Arne Asheim and Robert A. Gault Introduction Eudialyte, aNa-rich zirconosilicate with varying amounts of Ca, Fe, Mn, REE, Nb, K, Y, Ti, CI and F, was first described from the llimaussaq alkaline complex, South Greenland by Stromeyer (1819), Since then, the mineral has been described from many other alkaline deposits, and is a characteristic mineral in agpaitic nepheline syenites and their associated pegmatites. In recent years, eudialyte (sensa lata) has been the subject of extensive studies. The broad compositional variations and new insight into the crystal chemistry of the mineral group resulted in the definition of several new species by the Eudialyte Nomenclature Subcommittee under the Commission on New Minerals and Mineral Names of the International Mineralogical Association (Johnsen et al. 2003b). Brown eudialyte (s. I.) is a common constituent of the agpaitic pegmatites in the Langesundsfjord district in the western part of the Larvik plutonic complex (Br0gger 1890). Recent chemical analyses of the mineral have shown that some localities contain ferrokentbrooksite (Johnsen et al. 2003a). Other localities hold eudialyte (sensa stricto). Ferrokentbrooksite is the ferrous-iron-dominant analogue of kentbrooksite with Fe as the predominant element replacing Mn. Kentbrooksite is the Mn-REE-Nb-F end member in a solid solution series between eudialyte (s. s.) and ferrokentbrooksite, with an extension to oneillite (Johnsen et al. 1998, Johnsen et al. 1999, Johnsen et al. 2003a), as well as to carbokentbrooksite and zirsilite-(Ce) (Khomyakov et al. 2003). Carbokentbrooksite has a significant content of carbonate and Na > REE for the N4 site, while zirsilite-(Ce) has REE > Na (with Ce predominant) for the N4 site. -
12•12H2o, a New Mineral Species from Mont Saint-Hilaire, Quebec: Description, Structure Determination and Relationship to Benitoite and Wadeite

McDONALD§ Department of Earth Sciences, Laurentian University, Sudbury Ontario P3E 2C6, Canada ¶ GEORGE Y. CHAO Ottawa–Carleton Geoscience Centre, Department of Earth Sciences, Carleton University, Ottawa Ontario K1S 5B6, Canada ABSTRACT Bobtraillite is a new, complex zirconosilicate found in igneous breccias and nepheline syenite pegmatites at the Poudrette quarry, Mont Saint-Hilaire, Quebec. It is associated with a burbankite-group mineral, donnayite-(Y), clinoamphibole, albite, aegirine, pyrrhotite, pyrite, annite, analcime, microcline, a white mica (muscovite?), yellow titanite, clinopyroxene and calcite. Crystals are commonly grey to brown in color, blocky to prismatic, elongate along [001], with a maximum length of 2 mm. It is generally found as isolated single crystals or simple parallel intergrowths with two or three members, rarely in small (<0.1 mm) rosettes. It is transparent with a vitreous luster and a white streak, and is non-luminescent. The Mohs hardness is 5½; no cleavage is evident. It is brittle and has an uneven to conchoidal fracture. The calculated density is 3.16 g/cm3. Bobtraillite is nonpleochroic, uniaxial positive, with 1.627(1) and 1.645(1). Seven analyses made on one crystal gave: Na2O 5.62, CaO 1.11, SrO 17.76, BaO 0.40, B2O3 (calc.) 3.38, Y2O3 1.15, SiO2 40.51, ZrO2 25.32, HfO2 0.48, Nb2O5 1.32 and H2O (calc.) 5.25, total 102.30 wt.%, corresponding to (Na11.20Ca1.22)⌺12.42(Sr10.59Ba0.16)⌺10.75 (Zr12.69Y0.63Nb0.61Hf0.14)⌺14.07 Si41.64B6O132(OH)12•12H2O on the basis of 156 anions, or ideally, (Na,Ca)13Sr11(Zr,Y,Nb)14Si42B6O132(OH)12•12H2O. -

The Zr site usually has a small amount of Ti. M(1) is normally occupied mostly by Ca; the main substitutions are Mn, Rtt and Y.

Leaching of Rare Earths from Eudialyte Minerals
Western Australia School of Mines Leaching of Rare Earths from Eudialyte Minerals Hazel Lim This thesis is presented for the Degree of Doctor of Philosophy of Curtin University June 2019 Abstract Rare earths are critical materials which are valued for their use in advanced and green technology applications. There is currently a preferential demand for heavy rare earths, owing to their significant applications in technological devices. At present, there is a global thrust for supply diversification to reduce dependence on China, the dominant world supplier of these elements. Eudialyte is a minor mineral of zirconium, but it is currently gaining significance as an alternative source of rare earths due to its high content of heavy rare earths. Eudialyte is a complex polymetallic silicate mineral which exists in many chemical and structural variants. These variants can also be texturally classified as large or fine-grained. Huge economic deposits of eudialyte can be found in Russia, Greenland, Canada and Australia. Large-grained eudialyte mineralisations are more common than its counterpart. The conventional method of eudialyte leaching is to use sulfuric acid. In few instances, rare earths are recovered as by-products after the preferential extraction of zirconium . As such, the conditions for the optimal leaching of rare earths, particularly of heavy rare earths from large-grained eudialyte are not known. Also, previous studies on eudialyte leaching were focused only on large-grained eudialyte and thus, there are no known studies on the sulfuric acid leaching of rare earths from finely textured eudialyte. Additionally, the sulfuric acid leaching of eudialyte bears a cost disadvantage owing to the large volume of chemicals needed for leaching and for neutralising effluent acidity on disposal. -
