ABSTRACT:
Lithium carbonate can be efficiently produced from a brine by (i) removing the boron therefrom, (ii) diluting the boron-free brine, (iii) removing magnesium from the diluted brine, and (iv) adding sodium carbonate to thereby precipitate lithium carbonate. By diluting the boron-free brine, the co-precipitation of lithium carbonate during the magnesium removal process is greatly reduced, thereby improving the recovery and purity of the lithium carbonate.
