It is understood that the lithium carbonate produced in the pilot scale of this project meets the **industrial-grade lithium carbonate standards. Lithium extraction from brine refers to the processes of adsorption, filtration, and sedimentation of the lithium-containing brine obtained after the extraction of industrial salt, in order to obtain lithium carbonate and other lithium salt products; this is the main method for producing lithium carbonate. Lithium carbonate is a key product in the midstream of the lithium industry, and it is widely used in fields such as new energy vehicles, energy storage, and pharmaceuticals; it is referred to as \"white oil\". Among them, industrial-grade lithium carbonate and battery-grade lithium carbonate have a wide range of applications; compared to the former, the latter has higher purity and better performance. This time, the lithium carbonate produced using the company’s mother liquor is of industrial grade; in the future, this project is expected to produce battery-grade lithium carbonate with a higher added value. Since the launch of this project in November last year, the company has mobilized key personnel from the quality inspection and R&D center, Salt Production Plant No. 1, Salt Production Plant No. 2, and other units to form a dedicated team for the pilot phase of the lithium extraction project from brine. These teams have worked overtime to carry out research and development efforts, thereby accelerating progress on this project. The project is divided into four production stages: the adsorption stage, the membrane stage, the resin stage, and the evaporation and lithium precipitation stage. Its process differs significantly from the company’s existing production processes. In order to better carry out project development in collaboration with professional companies (organizations), the team members studied diligently at the production site and mastered the operation of the production equipment in the shortest possible time. At the same time, the team members planned in advance to ensure that the raw materials and water samples required for production were available ahead of time, which accelerated the progress of the project. During project development, sample testing is required throughout the entire process, which has led to a surge in the workload of the company’s quality control and R&D center. “We receive over 50 testing samples every day, so the workload has increased significantly compared to before. Moreover, the testing processes required for this project are more complex, and the accuracy of the test data is higher; therefore, we must work overtime, put in more effort, and strive to improve our work efficiency. ”The head of the company’s quality inspection and R&D center said. At present, the project has completed the pilot test for lithium extraction from brine at Salt Production Plant No. 1, and is currently carrying out research and development on mother liquor production at Salt Production Plant No. 2. “Building on the success of the pilot tests, we make full use of advantages such as production equipment to engage in discussions with companies in the vicinity that possess lithium mother liquor resources, exploring further possibilities for lithium extraction in order to accelerate the development of ‘new-type salt chemical productivity’. ”Shi Yongfei, the company’s vice chairman and deputy general manager, said.
