ABSTRACT:
Disclosed is a method for treating substantially homogeneous monocalcium phosphate (MCP) solutions that contain undesirable amounts of radium which comprises centrifuging these MCP solutions sufficiently to separate at least a portion of the radium from the solution. Such treated MCP solutions may then be reacted with sulfuric acid to simultaneously produce a phosphoric acid solution and a calcium sulfate precipitate such as gypsum having low levels of radium content.
