Lithium Carbonate Carbonation System
Industrial Evaporation & Crystallization Solutions
We provide Li₂CO₃ carbonation solutions for producing high purity lithium carbonate used in battery manufacturing
High-purity lithium carbonate is widely used in the production of advanced cathode materials for lithium-ion batteries, as well as in the preparation of battery-grade lithium fluoride. In the optoelectronic field, it serves as a key raw material for producing lithium tantalate and lithium niobate. It’s also applied in specialty optical glass, magnetic materials, supercapacitors, and pharmaceutical products.
Carbonate slurry is prepared by blending lithium carbonate with pure water and recycled mother liquor in a precise ratio. This mixture is pumped into the carbonation tower, where carbon dioxide gas is introduced under controlled pressure and temperature, resulting in the formation of lithium bicarbonate solution. The carbonated solution is filtered through a filter press and a precision filtration unit, then passes through a resin column for impurity removal. It subsequently flows into a continuous decomposition tower for further processing. The decomposed solution undergoes centrifugal separation to isolate solids. The wet material is then dried, screened, demagnetized, crushed, and packed to yield high-purity lithium carbonate. Part of the decomposed mother liquor is returned to the slurry preparation system, while the remainder is handled separately. The CO₂ generated during decomposition can be recovered, depending on market conditions.
