The luminescence intensity of zircon was stronger than that of xenotime after annealing at 1300 C, as shown in Fig. 5 (d) and Fig. S1 in the Supplementary Material. Therefore, the comparison of the green luminescence intensity of CL images before and after annealing at 1300 °C is an effective tool to distinguish zircon from xenotime in ores.
