Laboratory methods for analysis and investigation of complex uranium deposits

The data on laboratory techniques applied in analytical investigations of rock samples at any stage of the prospecting activity have been presented. Results of the investigations of the composition of uranium ores from blackshale thicknesses of paleozoic foundation as well as from the loose sedimentary cover have been generalized. Achievements of a laboratory in geotechnological studies of the extraction of uranium and subsidiary elements from ores have been demonstrated. (author). 6 refs
