Lithium carbonate is an important lithium compound, usually used in battery manufacturing, glass industry and pharmaceutical industry and other fields. The main process of producing lithium carbonate usually includes the following steps:

Lithium mining: The most common sources of lithium ore are hard rock lithium deposits, such as spodumene and lepidolite, and soft rock lithium deposits, such as lithium sulfide. These ores are usually mined and crushed into smaller lumps.

Ore leaching: Mined ore needs to be leached to dissolve lithium from the ore. The most common leaching methods are sulfuric acid leaching or hydrofluoric acid leaching.

Solution processing: Lithium is separated from the leaching solution by solution processing. This usually includes precipitation and filtration steps to remove impurities.

Carbonization reaction: The isolated lithium is usually in the form of lithium hydroxide (LiOH) or lithium chloride (LiCl). To make lithium carbonate, these lithium compounds are reacted with carbon dioxide (CO2) to form lithium carbonate (Li2CO3).

Lithium carbonate crystallization: The resulting lithium carbonate solution is crystallized to separate the lithium carbonate from the solution. This usually involves evaporating water from the solution, which causes the lithium carbonate to crystallize.

Lithium carbonate drying and refining: Lithium carbonate after crystallization usually needs to go through drying and refining process to improve the purity

Packaging and Shipping: Finally, the Lithium Carbonate is packaged and ready for shipping to industrial applications such as end users or battery manufacturers.
