[0002] Crude lithium carbonate is a lithium carbonate product with a high content of impurities. Lithium carbonate is an important lithium compound used in the manufacture of lithium-ion batteries, glass and ceramics and other products. Crude lithium carbonate is usually extracted from lithium ore, so it may contain other metal impurities such as sodium, potassium, aluminum, etc. During the production process, crude lithium carbonate usually needs to undergo further refining and purification processes to remove impurities and obtain high-purity lithium carbonate products. These purification processes may include melting, crystallization, dissolution, filtration and other steps to ensure that the final product meets industrial and battery grade requirements. The quality and purity of crude lithium carbonate directly affect the quality and performance of the final product. Therefore, in industrial production, the purification and refining process of crude lithium carbonate is very important.

However, the existing carbonization tanks are generally heated directly during heating, and the heating time is relatively long, resulting in low purification efficiency of the crude lithium carbonate.
