Abstract: In order to provide guidance for the efficient development and utilization of spodumene ore resources in China，based on the conclusion about the ores composition，texture，structure，main mineral embedded characteristics for the spodumene ore in China，the influence of process mineralogy characteris⁃ tics on flotation was further analyzed. The results showed that the spodumene ores of Songpan-Garze lithi⁃ um mineralization belt and Altay lithium mineralization belt have higher Li2O grade，and their structures are mainly massive structure. The embedded particle sizes are coarse，which is conducive to obtaining bet⁃ ter flotation indexes. The spodumene ores in Qinling lithium mineralization belt and Southern China lithium mineralization belt have lower Li2O grade，and their embedded particle sizes are fine. Therefore，it is diffi⁃ cult to develop the ores and production cost is larger. According to the process mineralogy characteristics of spodumene in China，it is suggested to pay more attention to the efficient and comprehensive utilization of spodumene in Sichuan and Xinjiang.
