Abstract

An aluminium chloride solution which may be obtained by treating calcined clay with hydrochloric acid (or with aluminium chloride solution enriched with hydrochloric acid) is evaporated to produce a crystal sludge from which mother-liquor is separated. The crystals are washed with hydrochloric acid or first with some of the original solution and then with pure hydrochloric acid (for instance of 20 per cent strength), the mother-liquor and washings being used to absorb hydrochloric acid arising from the calcination of the crystals to obtain alumina (when such calcination is effected), or from other sources and used, according to their content of iron either for washing the crystals or for treating more clay. When the solutions accumulate too much iron they are evaporated and calcined to produce hydrochloric acid.
