Theprojectuses lepidolite as raw material, with an annual output of 100,000 t/a battery-grade lithium carbonate. The construction drawing design of the first phase project with an annual output of 30,000 t/a lithium carbonate project is underway. The project uses rotary kiln to roast lepidolite, and the roasted clinker is leached for solid-liquid separation and online washing by plate-frame filter press. After continuous impurity removal and purification of the obtained brine, the finished lithium carbonate is obtained by continuous lithium precipitation process. The project is expected to be put into production in the middle of 2023.
