Development direction of uranium mining and metallurgy

At present, the biggest problems faced by uranium mining and metallurgy are the continuous decline of ore grade and deepening of mining depth, more and more complicated ore treatment, more and more difficult mining and metallurgy and higher production cost. A large number of low-grade, intractable marginal, sub-marginal and internal economic uranium resources will gradually become the main body of development and utilization. These low-grade resources are difficult to be economically utilized by conventional mining technology. Only by relying on the development and application of new technology, new equipment and new materials can we gradually expand the scope of uranium resources development and utilization and expand the amount of uranium resources available for development and extraction on the basis of continuously reducing the investment and cost of natural uranium extraction production in China and improving the efficiency of uranium extraction production.
