METHOD FOR EXTRACTION OF URANIUM FROM ORES Abstract of the Disclosure A method for continuously extracting uranium from ores comprises the steps of forming a slurry of ore in a leaching solution; heating the slurry while pumping it through a tube reactor at high turbulences characterized by Reynolds numbers in excess of 50,000; supplying gaseous oxygen at high pressures of at least 30 bar into the tube reactor such that the uranium is substantially completely oxidized in a soluble form but im- purities in the slurry are substantially kept from becoming soluble; recovering the uranium oxide solute which is substantially free of impurities.
