Research Status of Properties and Utilization of Lepidolite Lithium Slag

Lithium slag is the solid waste produced in the process of extracting lithium and its compounds from lithium-containing ore. The sodium salt and alkali remaining in the lithium slag of the lepidolite ore using the method of salt pressuring and autoclaving affect the safety of the environment. This article introduces the production, composition and physical and chemical properties of the lepidolite lithium slag, reviews its latest research progress in the field of building materials and functional materials, and analyzes the main factors restricting the use of lepidolite lithium slag and common problems in its applications. Finally, the application and development directions of the lepidolite lithium slag are prospected for the future drew lessons from the research of fly ash.
