The article generalizes results of many years-long research work undertaken by specialists of the Metallurgical Works and Processing Service of Priargunsky Mining and Chemical Works towards the large-scale modernization of the existing processing structure. The first system to be introduced was the circuit of complex uranium–molybdenum ore processing with the concurrent recovery of a marketable molybdenum-bearing product. In the early 1980s radiometric processing factory for ore with low uranium content was put into operation. Heap leaching plant using various economic leaching agents was built to process noncommercial ore reserves. The major success was introduction of grading of poor ore fragments using the method of X-ray radiometric separation. As a result of the accomplished lab-scale, semi-commercial and full-scale research and testing, a flexible uranium processing circuit was developed; it enabled efficient combination of hydrometallurgy, fine milling, heap leaching and X-ray radiometric separation. Adjustment of the preset limit of uranium content at check points allows varying ore feeds in diff erent processing schemes. As a consequence, it is possible to select optimal processing fl owcharts to reach maximum economic efficiency of uranouranic oxide production in the conditions of varied prices of fi nal uranium products, reagents and energy sources.
