ABSTRACT:
A process for removing radium from a radium-containing aqueous sulphate solution also containing dissolved magnesium at a pH not greater than about 10 comprises treating the solution with a soluble barium salt to precipitate radium as barium radium sulphate. The pH of the solution is raised to at least about 11 to precipitate an insoluble magnesium compound which collects the barium radium sulphate precipitate, and substantially all of the precipitates are separated from the solution.
