A simplified calcium oxalate and ferric hydroxide coprecipitation procedure was applied for quantitative separation and concentration of yttrium and the rare‐earth elements from eight USGS (STM‐1, RGM‐1, QLO‐1, SCo‐1, MAG‐1, SDC‐1, BHVO‐1, SGR‐1), three French (MA‐N, AN‐G, BE‐N), four South African (NIM‐35/71–38/71) reference rocks and one NBS coal (1632) before determination by flame and graphite furnace atomic absorption and optical‐emission spectroscopy. The results agree or fall near mid‐range of other published values, where available. The chondrite normalized distribution patterns are generally smooth and conform to the shapes of other analyzed samples of similar nature.
