Under the new economic conditions, the problem of decreasing substantially the cost of uranium in the final product obtained by processing mined ores has become acute. A search has shown that the problem can be successfully solved by closely combining hydrometallurgical conversion in plants with inexpensive processes, such as large-batch sorting in radiometric monitoring stations, radiometric piecewise separation, and mound leaching of low-grade ore. Radiometric enrichment produces tailings as well as average and rich concentrates. The rich concentrate will be processed using a separate scheme without a sorption process. A specific example of the combined scheme and the apparatus developed for implementing this scheme are examined. 1 figure, 3 tables, 10 references. |
