(Techsnabexport, Moscow)//boytsov/f/v/@tenex.ru DEVELOPMENT OF WORLD URANIUM INDUSTRY – KEY CHALLENGES By 2040, an 80 % increase in the uranium demand for in the world’s nuclear industry is projected. The gap between specified sources of uranium supply and requirements may amount to about 55 thousand tons of uranium. Low uranium prices are holding back geological exploration and development of new deposits. The world’s low-cost uranium resources are insufficient to meet long-term growth rates of uranium production which will satisfy global nuclear power industry demand. Keywords: uranium, demand, supply, resources, mining, production, discoveries. Р.3-10 |

(Institute of Nature Management of the National Academy of Sciences of Belarus, Minsk)//yaroslavgribik@tut.by FEATURES OF THE URANIUM POTENTIALITY OF SEDIMENTARY ROCKS AND FLUIDS OF THE PRIPYAT TROUGH The article considers the geological structure of the Pripyat trough, in the devonian deposits of which pre-salt, inter-salt and post-salt complexes of sedimentary rocks are distinguished. Their radioactivity was analyzed. It has been established that the distribution of uranium and radium in the oil deposits localized in them and near-edge formation waters are characterized by a significant shift of the radioactive balance towards radium both in near-contour formation waters and in oil deposits. The regulator of such movement is the volumetric concentration of radium in the places where the element passes from the rock to the aqueous phase. Keywords: Pripyat trough, uranium, groundwater, radiogeochemistry. Р. 34-39 |

Features of thorium geochemistry and mineralogy, the genesis and formation epochs of thorium-oriented geological rock associations, as well as the petrological composition and geology of a number of important thorium-bearing targets with complex ores are discussed. Their classification based on studying ore formations of the domestic metallogenic school and the IAEA is proposed. Examples of ore deposits of major geological and economic types are given. Lines for further studies are recommended. Keywords: thorium, metallogeny, mineral deposits, ore formations, zoning. Р. 39-46 |

(VIMS)// tubolcev@vims-geo.ru CASES AND PRACTICES OF IMPLEMENTING ISOTOPIC GEOCHEMICAL METHODS IN SEARCH FOR CONSEALED URANIUM DEPOSITES The paper dwells on the results of experimental studies on different types of uranium deposits that helped determine isotope-geochemical indicators of concealed uranium accumulation to be potentially used for exploration purposes. These include anomalies in the total alpha activity (plant bark and roots), mobile uranium, multiplicative and isotopic parameters (leached solutions from soil samples), 207Pb/206Pb ratios (geogas samples taken using charcoal collectors installed in shallow soil boreholes). Ground radiometric survey is necessary to exclude surface anomalies not associated with the ore bodies (the same results are obtained using a preliminary measurement of radon activity in charcoal collectors).

Sodium nitride was introduced during the precipitation process to form strong complex compounds. Achieved 99 % extraction of cobalt in the sediment. Studies have been carried out on the precipitation of nickel with sodium hydrosulfide from solutions purified from cobalt. A sulfur-containing concentrate with a content of 29 % nickel was obtained, which, after firing at T = 1080 oC, contained 87 % NiO, 0.13 Co, 0.78 Mn and 6.3 MgO.
