Series Description: This report outlines a study of the pilot plant format as a way to improve the RaLa process used from 1944-1950. It examines the precipitation steps and ion exchanges, which were evaluated for increased yield, reduced process time, and enhanced product purity. The report offers alternate processes for RaLa, such as centrifugation and an acetate-citrate ion exchange purification process.
