METHOD FOR PRODUCING ALUMINIUM HYDROXOCHLORIDE FROM BOEHMITE-KAOLINITE BAUXITES AND HYDROCHLORIC ACID

摘要

FIELD: chemistry.;SUBSTANCE: method for producing aluminium hydroxochloride from boehmite-kaolinite bauxites and hydrochloric acid involves bauxite dissolution in a steam steriliser with hydrochloric acid in the concentration of 200-300 g/l in ratio solid:liquid = 1:3-5 at temperature 150-225°C for 1-2 hours.;EFFECT: invention enables reducing power consumption, simplifying the process and increasing a recovery rate into an aluminium oxide solution.;1 tbl, 1ex
