We found that all the ores emitted similar levels of radiation (as seen on the graphs). This is because the ores were similar in that they all contained the same radioactive element: Uranium. Due to this we weren’t able to work out the most radioactive ore. Therefore we decided to work out radiation levels per gram (KeV/g) in order to get a Bibliography more accurate understanding of which ore emitted the most energy. This ore turned out to be Cuprosklodowskite which emitted 111068.2 KeV/g. Our weakest ore in terms of energy was Betafite which only emitted 9438 KeV/g. In •Wrightsrockshop.com 3rd place came Torbernite which emitted 20763.9 KeV/g. Pitchblende came a close 2nd emitting 107203.4 KeV/g. This last result came as a surprise. We hypothesised that Pitchblende would in fact be the most active ore which •Flickr.com turned out not to be true. Our hypothesis was backed up by some results however as Betafite did indeed turn out to be the least active ore. •Tumblr.com •Wikipedia.com Evaluation: •Irocks.com Our results for Pitchblende (and our results overall) were surprising. This is due to the figures we calculated for uranium content in each ore. In Pitchblende the overall uranium content was 88% whereas in Cuprosklodowskite this was 60%, also lower than some of the other ores we tested. The fact that Cuproslodowskite turned out to be the most radioactive ore tells us that our Pitchblende ore may have been older than our Cuproslodowskite ore. We may also say that our Pitchblende ore may not have been as pure as we expected it to be (this may be again because of its age). Looking back on our experiment we could’ve ensured all our ores were of similar mass as we had a range from 0.66 – 2.69 grams. This relatively large range could’ve been a factor in the outcome of our results. We could have also ensured that our ores were of similar age before we started the experiment as some ores may have been older and therefore contain less radioactive material compared to a newer ore which may have gone through less radioactive decay in its lifetime..

Antonio Carlos 6627 – Campus UFMG - Pampulha 30270-901 Belo Horizonte, MG [email protected] ABSTRACT The Lagoa Real uranium province is situated in the central-south of Bahia state – Brazil and it is presently by far the most important and best known uranium occurrence in Brazil. Nowadays 34 anomalies are known in a 30 Km long and 5 km wide area. An open pit mine was open in Cachoeira Mine, in the north portion of the area, and it is the only uranium mine in operation in Brazil and even in South America as well. The uranium mineralization in the Lagoa Real uranium province occurs in metamorphic rocks named albitites, due to their albite content (over 70%). Uraninite is the main uranium mineral, followed by pechblende, uranophane, torbernite and other uranyl minerals. Uraninite occurs as tiny round and irregular crystals (20 a 30 μm) included or associated to mafic minerals, mainly pyroxene and garnet, and also to amphibole and biotite and sometimes to albite. Some secondary minerals such as, for instance, uranophane, torbernite and tyuyamunite are also found. The main albitites minerals from the Cachoeira mine (plagioclase, garnet, biotite, pyroxene, amphibole and titanite) were studied by means of Infrared Spectroscopy Techniques.

  • Al~Hy and Dehydration of Torbernite
    326 The crystallog?.al~hy and dehydration of Torbernite. By A. F. HA~,~.IMOND, ~I.A., F.G.S. Assistant Curator, Museum of Practical Geology, London. [Read November 9, 1915.] I. CRYSTALLOGRAPHY. EASUREMENTS for torbernite have been given by numerous M observers; the results are, however, of rather early date, and althoug h the values for the ratio a:c are generally in fair agreement with the results here stated, the degree of accuracy of these measure- ments is not always indicated. Moreover, sevelml minor difficulties arise, add it has been suggested that some of the early descriptions refer to the allied species, zeunerite ; both species are optically uniaxial and possess almost the same axial ratios; they can, however, be dis- tinguished by means of their refractive indices. The ordinary index of all the specimens here described has been determined by the Becke method ; that for torbernite is 1.591, for the zeunerite from Schneeberg, approximately 1.62. A few torbernites possess a slightly higher index which may be due to the presence of zeunerite in isomorphous mixture, as is suggested by the presence of arsenic in some analyses. It has been possible to examine much of the original material described by L~vy in his catalogue of the Heuland-Turner Collection (3). ]3cfore the early measurements are discussed, an account will be given of measurements made on three well-crystallized specimens of torbernite, with the object of detelunining more closely the crystalline form of this mineral.

Box 158, Hungary 3Department of Environmental Engineering and Chemical Technology, University of Veszprém, 8201 Veszprém, P.O. Box 158, Hungary The mineral metatorbernite, Cu[(UO2)2(PO4)]2·8H2O, has been studied using a combination of energy dispersive X-ray analysis, X-ray diffraction, dynamic and controlled rate thermal analysis techniques. X-ray diffraction shows that the starting material in the thermal decomposition is metatorbernite and the product of the thermal treatment is copper uranyl phosphate. Three steps are ob- served for the dehydration of metatorbernite. These occur at 138ºC with the loss of 1.5 moles of water, 155°C with the loss of 4.5 moles of water, 291°C with the loss of an additional 2 moles of water. These mass losses result in the formation of four phases namely meta(II)torbernite, meta(III)torbernite, meta(IV)torbernite and anhydrous hydrogen uranium copper pyrophosphate. The use of a combination of dynamic and controlled rate thermal analysis techniques enabled a definitive study of the thermal decompo- sition of metatorbernite. While the temperature ranges and the mass losses vary from author to author due to the different experi- mental conditions, the results of the CRTA analysis should be considered as standard data due to the quasi-equilibrium nature of the thermal decomposition process.

The environmental relevance of these V-phases arises from their low solubility at most surface and groundwater conditions, where they can ultimately control aqueous V levels. In the present work, samples of naturally occurring uranyl phosphates from the Tarabau site, included in the Nisa deposit, located in central-eastern Portugal, are studied with X-ray diffraction (XRD), Electron Micro­ probe (EMP) and Scanning Electron Microscopy, with the purpose of i) identifying uranyl phosphate mineral Keywords: paragenesis, ii) assessing chemical homogeneity and stoichiometry of the most relevant phases and iii) unra­ Uranyl phosphate veling possible textural features of mineral reequilibration processes.
