摘要:
Disclosed is a method for producing high-purity lithium carbonate. The method includes: removing magnesium and boron from a brine; separating and removing the remaining magnesium and calcium; concentrating the resulting brine by spray drying to form a powder; washing the powder to concentrate lithium; and carbonating the lithium ions with sodium carbonate (Na2CO3).
