Process for preparing lithium chlorate by lithium extracted from lepidolite
InactiveCN1827527AReduce energy consumptionReduce investmentLithium carbonates/bicarbonatesLithium carbonateSulfate
The invention relates to a method for preparation of lithium carbonate extracting lithium from lithionite. The invention consists of milling, leaching and filtering after modifying by broasting lithonite ore together with the additive findings such as calcium fluoride, calcium sulfate and sodium sulfate at a certain temperature, adding sodium carbonate into the leachate to deposite lithium ion forming the deposition of lithium carbonate, and washing and drying the solid gained by filtering to get the product of lithium carbonate. The filtered mother liquid returns to the circulation to deposit lithium ion. After secondary circulation, we get the mixed salts of potassium sulfate and sodium sulfate as the educts by washing and drying the aforementioned filtered mother liquid. Some of the mixed salts return as findings roasted with lithonite ore for circulation use, while others can be used as raw material for preparation of potassium sulfate.
