Abstract: Boron is removed from aqueous solutions by heating the solution to 60.degree.-100.degree. C. and adding a calcium compound such as lime to form a precipitate of calcium borate which is separated such as by filtration. Improved results are obtained by using other calcium salts such as calcium chloride in combination with lime. For solutions initially containing less than 100 ppm boron, calcium borate seed crystals are introduced.
