Abstract

See full text

This invention refers to a novel process for obtaining high purity magnesium hydroxide from a solid starting material containing magnesium in the form of, and/or combined with, carbonates, oxides and/or hydroxides, either natural or synthetic. The process comprises leaching the starting material to dissolve the magnesium; the solution is treated with alkali to precipitate the high purity magnesium hydroxide, and the remaining mother liquor is fed to a regeneration step of both the alkali used in the precipitation of high purity magnesium hydroxide, and the acid for leaching. The process of the invention is characterized by recycling reactants (acid and alkali) regenerated in the same process.
