METHOD FOR CONCENTRATING METAL CHLORIDES IN AND SEPARATING SAME FROM AN IRON(III) CHLORIDE-CONTAINING HYDROCHLORIC ACID SOLUTION

摘要

A method for concentrating metal chlorides in and separating same from an iron(III) chloride-containing hydrochloric acid solution is described, wherein iron is precipitated from the solution as iron oxide, preferably haematite and filtered off in a filtration device, and the now further concentrated non-hydrolysable metal chlorides are removed from at least a part of the hydrochloric acid filtrate.
