Radiometric sorting of ore in in-situ uranium leaching

The article analyzes present-day technological innovations in in-situ borehole leaching of uranium, and discusses their influence on eco-friendliness, safety and efficiency of the process. The authors describe the key aspects of modern approaches to radiometric sorting of uranium ore, including automation, machine learning and other novel techniques, and discuss economic efficiency of radiometric separation of uranium ore. For the control of operating conditions in in-situ leaching, a system of automatic control with the dynamic pulse–frequency modulation is proposed. The system features high interference immunity and simplicity of hardware and software implementation. In addition, the scope of the discussion embraces prospects of technological advance in this area of research and potential contribution of new technologies to the environmental impact mitigation, mineral mining efficiency and sustainable development of the mining industry.
