It's very easy for a Hydroxide facility to split out the Carbonate, it is already in the process, just needs finishing touches.
Yes, it is very straightforward to separate or produce Lithium Carbonate at a Lithium Hydroxide facility. Because Lithium Hydroxide is highly soluble compared to Lithium Carbonate, facilities can selectively precipitate the carbonate out of the hydroxide solution by introducing carbon dioxide.The Separation and Conversion ProcessThe chemical separation process uses existing Lithium Hydroxide equipment and typically follows these steps:Carbonation: Carbon dioxide gas (CO₂) is sparged or bubbled directly into the aqueous Lithium Hydroxide solution.Precipitation: As the CO₂ reacts with the Lithium Hydroxide, it forms insoluble Lithium Carbonate, which precipitates out of the liquid:2LiOH + CO₂ → Li₂CO₃ + H₂OFiltration: The mixture is pumped through industrial clarifiers and filters to physically separate the solid Lithium Carbonate from the liquid.Drying: The solid precipitate is then typically dried at around 95 ° C to eliminate any excess moisture, yielding a highly pure product.
