Abstract

In the process of the parent Specification wherein clay or other aluminous material is treated with hydrochloric acid and the solution is evaporated to obtain aluminium chloride crystals which are washed with hydrochloric acid to obtain pure aluminium chloride, the mother-liquor and washings being enriched with hydrochloric acid and used again until they become too rich in iron chloride, these ferruginous liquors are according to the present invention diluted and brought into reaction with aluminous material such as burnt clay to remove most of the iron and enrich the liquors in aluminium chloride. The liquors can then be evaporated as in the process of the parent case and the clay is washed with water to remove the iron hydrate, after which the clay may be used with other raw material in the process.
