Abstract

Process for the production of magnesia, characterized in that it comprises simultaneously draining and compacting a magnesium hydroxide sludge, to give a magnesium hydroxide cake containing at least 67.5% by weight of solids and having a mass density, green, at least 1.15 g/cc; and converting the cake thus obtained, by means of a suitable heat treatment, into magnesium oxide.
