Abstract.
A methodological approach to economic evaluation of producing uranium oxides from deposits with underground mining is presented for poor and extremely poor ores. Source data were determined for preliminary economic evaluation of leaching in underground conditions. A calculation scheme was adapted to the Vatutinsky deposit in terms of feasibility of uranium ore producing, which was based on the approbated world practices for evaluating economics of mineral deposits and analyzing effectiveness of investments into the mineral mining. According to the algorithm of calculating the stages of uranium ore mining the following indices were defined: preliminary costs of drilling and blasting operations for weakening ore massif in sandwiched zone; costs of drilling operations and equipping of feeding and receiving boreholes-injectors with the cost of materials; cost of leacheable agents with taking into account their concentration and possible losses; pipelines and their construction cost, number and type of pump equipment for transporting leaching and productive solutions to the surface and into the chamber, respectively; cost of construction of an underground tank contour for productive solutions; cost of structures and works on the surface; the construction of underground protective walls that would prevent sulfuric acid fumes leaking from the drilling rooms into mine atmosphere; labor costs, and so on. The resulted cost of the uranium oxides producing was compared with the similar technological indicators, which are used at the Vatutinsky deposits. Conclusions made concerns a possibility to use the proposed technology for the conditions under the consideration.
Key words:
cost of uranium mining by a geotechnological method, uranium ore, uranium oxide, calculation of leaching technology economic efficiency, leaching of ores.
