Abstract:With the vigorous development of the new energy industry, the dependence on lithium resources is also increasing. How to extract lithium from lithium-containing ore efficiently, environmentally and economically has become an urgent problem to be solved in the development of lithium battery energy. Lepidolite is one of the important sources of lithium extraction from ore, our country has abundant lepidolite reserves. How to efficiently and economically decompose lepidolite and extract lithium and other valuable metals has become an urgent problem and research that needs to be solved in the comprehensive treatment of lepidolite focus. This article analyzes the current lithium extraction technology of lepidolite, compares the advantages and disadvantages of different lithium extraction method, and draws the conclusion that a single lithium extraction method will be replaced by multiple lithium extraction technologies in the future. In the future, the technical development of the new lithium extraction process of lepidolite lies in reducing the output of lithium slag or resource utilization of lithium slag, and realizing the comprehensive utilization of associated resources.
Key words: lepidolite; lithium extraction technology; roasting; valuable metals; comprehensive utilization
