Production process of sodium carbonate pressure leaching
Due to the disadvantages of the process of producing lithium carbonate by sulfuric acid method, the process is long and the process energy consumption is high. Carbonization process is adopted to prepare carbonic acid
Lithium, better than sulfuric acid process. In production, the process of product washing and sodium evolution is saved, the operation is simplified, and the energy consumption is saved.
The process firstly grinds the β-spodumite processed by spodumite to about 200 mesh, then adds 3.5~7 times sodium carbonate according to the ratio of Li2O, and then compresses and leaches in the reactor under pressure at 200℃, and introduces CO2 gas to generate soluble LiHCO3
Solution, filter to remove residue (zeolite), heat to 95℃ to expel CO2, precipitate, filter, filter cake drying to obtain lithium carbonate products.
Other methods:
In addition to the above extraction of lithium carbonate from lithium ores such as spodumite or lithium mica, there is also the production process of producing lithium carbonate from brine, such as evaporation precipitation production process, calcination production process, solvent extraction production process, aluminate precipitation production process, adsorption production process, electrodialysis production process, etc. In addition, there is also the production process of extracting lithium carbonate from seawater.
