The Effect of Boron Forms on the Crystallization Process of Lithium Carbonate

The present study investigates the effect of low concentrations of boron on the crystallization of lithium carbonate (Li 2 CO 3 ). Experimental results indicate that the boron in brine mainly exists in the forms of boric acid (B(OH) 3 ) and borate anion (B(OH) 4 − ). Temperature and pH are critical factors to adjust the ratio of B(OH) 3 and B(OH) 4 − . Meanwhile, the density functional theory calculation results suggest that the interaction of...
