Research on extracting high-purity lithium carbonate from lithium salt lake brine and its resource u

High-purity lithium carbonate is produced from lithium mixed with salt through the dressing and enrichment of lithium salt, then carbonization. After a pilot test for producing 50 tons/yr of high-purity lithium carbonate was completed, the product met electronic-grade lithium carbonate requirements and the refined lithium carbonate yield was not less than 92 percent.
