Intelligent pre‑sorting method for spodumene ore combining X‑ray transmission (XRT) and deep learning: Promoting energy conservation and emission reduction in mines

The global rise in lithium demand, driven by the expansion of the new energy sector, underscores the need for efficient mineral processing of spodumene, the primary lithium ore. This study addresses key challenges in current pre-sorting systems, including low sorting precision, high energy consumption and limited real-time adaptability, by developing an intelligent X-ray transmission (XRT) pre-sor...
