Background Art

The calcination-sulfuric acid leaching method is the most commonly used method for preparing lithium carbonate: its processing steps are: 1. Calcine spodumene to convert the mineral component of spodumene from α to β, making it easily soluble in sulfuric acid. 2. React it with sulfuric acid and heat it to form lithium sulfate. 3. Add water and calcium carbonate to lithium sulfate, remove impurities by filtering, and prepare a lithium sulfate aqueous solution. 4. Add soda ash and quicklime to the filtrate to make it alkaline, filter out impurities, neutralize the filtrate again with sulfuric acid, and evaporate it to prepare a Li2SO4 solution with a concentration of about 3%. 5. Add soda ash to the solution and heat it to precipitate it. The precipitated substance is lithium carbonate, so the final step requires an extraction device to precipitate and extract the lithium carbonate.
