The invention is a process for the removal of radium from acidic aqueous solutions In one aspect, the invention is a process for removing radium from an inorganic-acid solution The process comprises contacting the solution with coal fly ash to effect adsorption of the radium on the ash The radium-containing ash then is separated from the solution
Due to the extremely low concentration in the ore and the difficulty of separation at the time, the price per gram of the material was exorbitant, ranging into the millions in today's dollar figur  The ore needed for the production of Radium could only be gotten from a single place on the planet, Joachimsthal
After uranium is extracted from rock, the processes leave behind radioactive waste Uranium eventually decays to radium, and then radon Open pit uranium milling and in situ mining sites do not pose a radon risk to the public or miners
Neither of the deposits is mined for radium but the uranium content makes mining profitable The Curies' process was still used for industrial radium extraction in 1940, but mixed bromides were then used for the fractionation If the barium content of the uranium ore is not high enough it is easy to add some to carry the radium These processes .
One ton of uranium ore contains only about 014 grams of radium Today, radium can be obtained as a byproduct of refining uranium and is usually sold as radium chloride (RaCl2) or radium bromide .
