RESEARCH ON THE REMOVAL OF RADIUM FROM URANIUM

contents of radium always exist in association with higher grades of uranium ore As environmental awareness increase and more stringent environmental protection requirements develop, the demand for rigid industrial effluent discharge standards increases So the removal of the radium is an important step in uranium effluent process treatment because radium is a main radionuclide in uraniumSeparation study of uranium and radium as their mixed oxides from the uranium ores was conducted by the reaction with NaCl or NaOH molten salts followed by leaching with dilute HNO 3 with the aim of decontamination of the ore tailing When the ore was heated in the NaCl melt bubbling with nitrogen or oxygen, even though 50% of uranium remained in the residue, the amount of radium in theRemoval of uranium and radium from uranium ores byBorrowman, SR, and Brooks, PT, 1975, Radium removal from uranium ores and mill tailings: US Bureau of Mines Report of Investigations RI 8099, 12 pRadium removal from uranium ores and mill tailings | AZGS

How is Radon Linked to Uranium?

Uranium is the first element in a long series of decay that produces both radium and radon Uranium is often referred to as the "parent element" and both radium and radon are referred to as the "daughters" Since uranium is present in all rocks and soils, so are radium and radon because they are the "daughter products" that are formed by the radioactive decay of uranium Radioactive decayThe ore was concentrated at Radium Hill by heavy media separation and flotation to produce a concentrate containing about 07% uranium The mineral form was mostly davidite, making it difficult to treat This concentrate was railed 300 kilometres to a treatment plant at Port Pirie where it was subject to hot acid leaching The plant was designed to produce 160 tonnes of uranium oxide per yearFormer Australian Uranium Mines World Nuclear
