Method of Extracting Boron from Natural Brines

摘要

The object of the invention is a method of extracting boron from natural brines. For a more thorough extraction of boron, the brine is treated with a mixture of lime with aluminum sulfates, or with salt of trivalent iron (for example, chloride, or sulfate), the deposited residue of hydrate of aluminum oxide of hydrate of ferric oxide is separated with absorbed boron from the mother liquor, the residue is processed with sulfuric acid or an iron sulfate solution to transform the boron into solution, and the boron is deposited from it by the known method.
