Abstract: Lithium extraction from lepidolite plays a non−negligible role in the global supply of lithium salts.The paper reviews the physical beneficiation enrichment of lepidolite and the method of chemical extraction of lithium carbonate from lepidolite concentrate.The primary method of lepidolite beneficiation enrichment is flotation, conventional cationic collectors have strict requirements for the collecting environment, and it is necessary to carry out research on new cationic collectors and combine different anionic collectors to improve the collecting efficiency. Among the chemical methods for extracting lithium from lepidolite, sulfate roasting is currently the most mature method. The limestone roasting method has been phased out by the market due to its high energy consumption and cost; the sulfuric acid method has a high leaching rate, but it requires a large amount of alkali for waste liquid neutralization; the chlorination roasting method and the pressure boiling method have high equipment requirements, leading to poor process operability. Looking forward, the next generation technology of lithium extraction from lepidolite should focus on enhancing the extraction of valuable metals, producing high value−added products, high−value disposition of lithium slag and comprehensive utilization of associated resources.
