Separation of aluminium and iron chlorides by salting out method

Results of research the separation of aluminium and iron chlorides after dissolution the boehmite-kaolinite bauxites in hydrochloric acid are presented. The conditions influencing on the content of main impurity in aluminum chloride hexahydrate are studied. Various approaches on washing the received crystals from uterine solution are investigated. The received results allow to receive the aluminum chloride hexahydrate, necessary for further thermohydrolysis within hydrochloric acid technology of receiving metallurgical alumina.
