Abstract

Sodium aluminate solutions obtained from bauxite, are, after completion of the dissolving, brought to the conditions necessary for precipitation of alumina by mixing, without release of pressure, with lyes which have been used for washing alumina or have already had alumina extracted from them. Specification 757,825 is referred to.
