Abstract
A process for obtaining magnesium oxide by wet process, starting from a double carbonate of magnesium and calcium as dolomite, characterized in that the mineral or raw material, finely ground, is subjected, under ambient conditions, to a succession of operations consisting of: sulfation, to obtain calcium and magnesium sulfates, the former in precipitated form, and the latter in dissolved form; filtration, to separate the precipitate of calcium sulfate from the magnesium sulfate solution, obtaining calcium sulfate as a by-product; Causticification, with a suitable alkali, of the magnesium sulfate collation, obtaining a precipitate of magnesium hydroxide and an alkali metal sulphate solution used, this alkali metal solution used for the causticization being subjected to a crystallization operation and resulting in crystallized sulfate as another byproduct of the process; and heating the precipitated magnesium hydroxide to remove its water of hydration, thereby obtaining anhydrous magnesium oxide, as a product of the process.
