Effect of Carbonation Temperature on the Purification of Lithium Carbonate

Abstract:

High-purity Li₂CO₃ was purified and prepared by carbonation decomposition method using industrial Li₂CO₃ as raw material. The effects of carbonation temperature on the purity, productivity and the removal of impurities containing Ca, Mg, Fe, Cu and Ni in purification process were investigated. The results shown that high carbonation temperature didnt benefit the purity and productivity of Li₂CO₃. The content of Mg decreased with the increase of carbonation temperature. The other impurities, such as Ca, Fe, Cu and Ni, had no obvious change with the increase of carbonation temperature. The optimum carbonation temperature was determined as 25°C.
