At present, the global production of 45,000 tons of lithium is obtained by molten salt electrolysis using lithium chloride as a raw material. Due to the release of chlorine gas in the production process, the environment is seriously polluted and the energy consumption is high. In this paper, lithium carbonate is used as a raw material, and aluminum powder is used as a reducing agent to extract metal lithium in a vacuum reduction furnace by aluminothermic reduction. The lithium recovery rate is 85% and the purity of metal lithium reaches 99.5%. In the laboratory, a continuous vacuum lithium reduction furnace was developed. No harmful gases were released during the entire production process. It was environmentally friendly.The production of lithium by aluminothermic reduction is a very promising method. The continuous lithium vacuum reduction furnace is the key equipment of this process, which lays the foundation for future industrial application.
