粗级碳酸锂提纯工艺过程研究

Abstract

Abstract: Lithium carbonate（Li₂CO₃） is widely used in the fields of ceramics，metallurgy，energy，and pharmaceutical etc..A lot of practical applications of Li₂CO₃ need high purity，but the Li₂CO₃ that extracts directly from the salt lake brine are difficult to meet the requirements due to existing technology and the limitations of the salt lake brine itself.Based on the practical requirements，carbonation-decomposition method to get high-purity Li₂CO₃ from the coarse Li₂CO₃ products was studied.The effects of carbonation conditions，such as CO₂ flow rate，carbonation time，carbonation temperature，and the ratio of solid to liquid，on the dissolution of coarse Li₂CO₃ were also investigated.Results showed through the simple process the purity of Li2CO3 could increase from 88% to more than 99%，and the yield of the all process could reach more than 75%.

Key words: lithium carbonate, purifying process, carbonation-decomposition method
