Certain rare earths possessing high thermal neutron absorption cross sections, when present in only trace quantities in metals used in nuclear technology, must be separated before a satisfactory spectrographic determination can be made. These rare earths are separated from beryllium and magnesium by precipitation as oxalates with added thorium as a carrier. The thorium is removed by an 8-quinolinol extraction leaving a residue suitable for spectrographic analysis. With zirconium, titanium, uranium, and stainless steel, a preliminary fluoride precipitation is made. At least 96% of the rare earths are consistently recovered.
