| Abstract: |
| As a strategic and critical raw material both in China and globally, beryllium faces an increasingly prominent supply-demand imbalance. In China's Shizhuyuan tungsten-polymetallic deposit, associated beryllium resources remain underutilized due to their complex occurrence state, leading to long-standing technical challenges of "difficult separation, low recovery, and high loss", hindering their full, high-value, and green exploitation. This study systematically investigates the process mineralogy of beryllium-bearing minerals in the Shizhuyuan deposit using optical microscopy, electron probe microanalysis (EPMA), energy-dispersive X-ray spectroscopy (EDS), and automated mineralogy (AMICS) to clarify the occurrence state of beryllium. The results reveal that the deposit contains 0.069% BeO, with beryllium primarily hosted in independent minerals: 47.95% in chrysoberyl, 39.31% in phenakite, and 12.74% in beryl. The beryllium minerals exhibit fine-grained dissemination (mostly below 0.043 mm) and are closely intergrown with muscovite and fluorite, significantly complicating their recovery. To enhance beryllium extraction, a combined beneficiation-metallurgy approach under fine grinding conditions is recommended. |
