During the study of the Bayi copper deposit, scheelite was discovered and confirmed in copper-bearing veins by field fast X-ray Fluorescence Spectrometry (XRF) analyzer, fluorescent lamp, optical microscope and electron probe. The discovery of scheelite in the Bayi copper deposit veins is not only important for the further study of regional tungsten metallogenic regularity in China, but also helpful for tungsten prospecting in the Zhongtiaoshan area.
