The invention belongs to the wet-process metallurgical filed and in particular relates to a method for preparing
titanium solution by wet-
processing on
vanadium-
titanium magnetite concentrates. The method for preparing
titanium solution by wet-
processing on
vanadium-titanium
magnetite concentrates comprises the following steps of: (1), mixing the
vanadium-titanium
magnetite concentrate with
hydrochloric acid, and leaching to obtain an intermediate
sizing agent; (2), filtering the intermediate
sizing agent to obtain leaching liquor and leaching residues; (3), carrying out water-washing on the leaching
slag to obtain washing water and washing
slag; (4), carrying out fused-salt reaction on the washing
slag to obtain fused-salt reaction materials; (5), carrying out water-washing and filtering on the fused-salt reaction materials to obtain water-washing materials; (6), carrying out acid
pickling on the water-washing materials to obtain
sizing agent, and filtering to obtain the acid-pickled sizing agent; (7), carrying out acid dissolving on the acid-pickled materials by using a
sulfuric acid solution to obtain acid-dissolved materials; and (8), adding the acid-dissolved materials to the
sulfuric acid solution for extracting, and filtering to obtain extracting solution which is the titanium solution. According to the method for preparing titanium solution by wet-
processing on vanadium-titanium magnetite concentrates disclosed by the invention, the titanium in the iron concentrate is sufficiently utilized, so that the titanium
resource utilization rate is high and the
recovery rate of the titanium in the titanium concrete is higher than 90%.
