During the development of rocky uranium deposits, the quality of extracted ores
(first of all, the uranium content in ores) is subjected to change during the technological
processes of exploration, opening, preparation, cutting, extraction and ore preparation
before processing the extracted mineral raw materials. At each stage, a certain
level of the content of the useful component in the ores is formed. The main task of the
entire mining complex is to obtain the quality of ores that will ensure maximum extraction
of uranium first from the bowels, and then from the ore prepared for processing.
At each stage of mining operations, technological techniques are used that allow
the mineral raw materials to be prepared as well as possible for the next stage. The
complex of these technological techniques makes it possible to obtain the necessary
ore quality to obtain the finished products of a mining enterprise with minimal costs and with the maximum level of a useful component extraction into a natural uranium
concentrate. During mining complex ores contain other useful components besides
uranium, usually molybdenum, so, the same requirements are imposed on molybdenum
concentrate. Extraction of associated components into finished products makes
it possible to solve one of the main tasks of extraction of mineral raw materials – the
integrated use of subsurface resources. The Priargunsky Mining and Chemical Production
Association has developed an algorithm for managing the quality of extracted
ores, consisting of a number of technological stages, at each of which operations
are carried out that together achieve the maximum economic effect in the production
of finished products. The article presents an algorithm for managing the quality
of mined ores during the development of rocky uranium ores at the Streltsovsky ore
field deposits. |
