Abstract:

During the study a possibility of using leaching technologies (a combined method) while extracting uranium ore was considered. Stages of uranium produce is shown by comparing two different extraction technologies. Technological processes of uranium mining and a proposed procedure of combined operations are considered. An algorithm for calculating primary parameters of the leaching in stoping chambers was developed. Parameters of rock weakening before leaching were determined. Preliminary estimates of timetable for leaching depending on the physical and chemical properties of rocks, reagent consumption, list of additional works, etc. are given. As a result of the research effectiveness of the proposed technology and flow sheets for leaching under the conditions of the Novokonstyantynivka deposit has been proved.

Keywords:
