Abstract:With the rapid development of the new energy industry, the global demand for lithium salt grows rapidly. The existing lithium extraction processes from lithium-bearing ores generate a substantial amount of lithium slag, with annual emissions in China exceeding 15 million tons. The comprehensive utilization rate of this slag is relatively low, primarily directed towards the construction materials sector, such as cement and concrete. However, as related standards become increasingly stringent, the large-scale utilization of lithium slag has emerged as an urgent issue that needs to be addressed. Based on the discussing of the application of lithium slag in the preparation of building materials and the synthesis of inorganic materials, The high-value utilization methods such as the recovery of metal resources from lithium slag, the production of zeolite molecular sieves were summarized. Furthermore, the large-scale ecological reclamation strategies of soilization for the disposal of lithium slag were proposed. It provides recommendations for the resource utilization and large-scale consumption of lithium slag, and escorts the vigorous development of lithium salt industry.
