Box 100 1400 Vienna, Austria WORLD DISTRIBUTION OF URANIUM DEPOSITS (UDEPO) WITH URANIUM DEPOSIT CLASSIFICATION IAEA, VIENNA, 2009 IAEA-TECDOC-1629 ISBN 978–92–0–110509–7 ISSN 1011-4289 © IAEA, 2009 Printed by the IAEA in Austria October 2009 FOREWORD Having comprehensive information on the worldwide uranium deposits is crucial for implementation of significant nuclear power programmes in the world, especially with the increasing interest in nuclear power and concerns about the supply of energy resources. Starting from the early years of the development of nuclear energy for peaceful uses, the International Atomic Energy Agency has published numerous reports on different types of uranium deposits, their geological characteristics and geographical distribution. With the increased amount of information available on uranium deposits throughout the world, the IAEA was able to establish an electronic database and publish it in the form of an Atlas in 1995. The atlas later was supported with a World Guidebook to Accompany IAEA Map: World Distribution of Uranium Deposits, in the form of a databook in 1996. The name of the database was World Distribution of Uranium Deposits (UDEPO). The UDEPO database was revised and expanded in 2004 to store to provide more detailed information on uranium geology and technical characteristics of the deposits. The revised database has been published on the internet since 2004. The database and its web site are being updated continuously. This report and its attached CD-ROM contain information on 878 uranium deposits worldwide and reflect a snapshot of the database as of end of 2008. The database itself is being updated continuously. The reader can access the most up to date information at www- nfcis.iaea.org. The IAEA wishes to thank the consultants who took part in the preparation of the UDEPO database. The IAEA is also grateful to the Member States and individual organizations for their generous support in providing experts and data to make this database more complete. The IAEA officer responsible for this publication was M. Ceyhan of the Division of Nuclear Fuel Cycle.

Though trade restrictions continue to impede completely free access to the worldwide uranium market, the uranium resources and production capabilities of the developing countries are becoming increasingly important in assuring the adequacy of uranium supplies to meet projected worldwide demand. Therefore, papers presented at this meeting provide an important overview of uranium production operations in developing countries as well as offering insight into future production plans and potential. Along with their increasing contribution to worldwide uranium supply, the environmental impact of uranium production in developing countries has come under increasing scrutiny

  • Heavy Mineral Sands in Brazil: Deposits, Characteristics, and Extraction Potential of Selected Areas
    minerals Case Report Heavy Mineral Sands in Brazil: Deposits, Characteristics, and Extraction Potential of Selected Areas Caroline C. Gonçalves and Paulo F. A. Braga * Centre for Mineral Technology (CETEM), Av. Pedro Calmon 900, Cidade Universitária, Rio de Janeiro 21941-908, Brazil; [email protected] * Correspondence: [email protected]; Tel.: +55-21-3865-7222 Received: 15 January 2019; Accepted: 6 March 2019; Published: 13 March 2019 Abstract: In Brazil, heavy mineral sand deposits are still barely exploited, despite some references to Brazilian reserves and ilmenite concentrate production. The goal of this project is to characterize and investigate the potential recovery of heavy minerals from selected Brazilian placer occurrences. Two areas of the coastal region were chosen, in Piaui state and in Bahia Provinces. In all samples, the heavy minerals of interest (ilmenite, monazite, rutile, and zircon) were identified by scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques and also quantified by X-ray fluorescence spectrometry (XRF) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The total heavy minerals (THM) in the Piaui samples were 6.45% and 10.14% THM, while the figure for the Bahia sample was 3.4% THM. The recovery test of the Bahia sample, using only physical separation equipment such as a shaking table and magnetic separator, showed valuable metallurgical recoveries at around or greater than 70% for each stage, and the final concentrate of pure ilmenite was composed of up to 60.0% titanium dioxide after the differential magnetic separation. Another aim is to compile accessible information about Brazilian heavy mineral main deposits complemented with a short economic overview.
