Aegirine, “perrierite‐(Ce)”, and ferrocolumbite, occurring in the Bayan Obo Nb‐REE‐Fe deposit in Inner Mongolia, China, contain appreciable amounts of scandium. The Sc 2 O 3 content in aegirine (sample TS‐15) was 0.34–1.81 wt% (with one exceptionally high value of 3.45%) with an average value of 1.19%. The Sc 2 O 3 content of “perrierite‐(Ce)” (TS‐20) was 2.82–3.64% with an average value of 3.26%. In the ferrocolumbite samples (TS‐16, TS‐23), the Sc 2 O 3 content was 0.20–0.25% with an average value of 0.22% in sample TS‐16, and 0.56–1.04% with an average value of 0.67% in sample TS‐23. These data provide the basic information for future possible recovery of scandium as a by‐product from the deposit.
