LEACHING OF ASHES OF CARBONACEOUS URANIUM ORE WITH SULPHURIC ACID. Report No. 85/IV

Technical Report ·
OSTI ID:4208980
In order to compare acid and alkaline methods of processing carbonaceous uranium ore and to investigate the leaching of ashes of such ores, preliminary studies on leaching with sulfuric acid were carried out. The results suggest practicability of processing ashes with dilute sulfuric acid when the ore is roasted, or additionally reroasted with sodium bisulfate in a temperature of 600 deg C. Good results are obtained by mixing carbonaceous and non-carbonaceous ores, which makes it possible to use roasting temperatures of 600 deg C or below. Combustion at temperatures above 600 deg C adversely affects leaching of ashes. (auth)
