Radium of radium Curie used the residues after extraction of uranium from pitchblende. The uranium had been extracted by dissolution in sulfuric acid leaving radium sulfate, which is similar to barium sulfate but even less soluble in the residues. The residues also contained rather substantial amounts of barium sulfate which thus acted as a carrier for the radium sulfate. The first steps of the radium extraction process involved boiling with sodium hydroxide followed by hydrochloric acid treatment to remove as much as possible of other compounds. The remaining residue was then treated with sodium carbonate to convert the barium sulfate into
Radium (horse) campdrafting without a bridle. In circa 1928, Radium was sold to Herb O’Neil, who, as a friend of Donald Beaton, had ridden the horse in competitions for Beaton when he had been unable to get away from his property. Herb O’Neill competed extensively with Radium, winning over a large area of the state. Just prior to the Second World War (WWII), Radium won a Championship Campdraft at Kempsey, New South Wales with the next ten placings going to Radium’s sons and daughters. Radium was also highly successful in led contests for the best type of Stock Horse. During WWII, at
