摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a ferric chloride solution in which the production process is easy, the cost is low, and also the quality is high.SOLUTION: A hydrochloric acid recovery manufacturing process in which a hydrochloric acid pickling waste liquid is used as a raw material comprises as follows. Iron oxide and hydrochloric acid are generated by a roasting reaction of the following formula (1) 2FeCl+1/2O+2HO→FeO+4HCl (1), next, the generated hydrochloric acid is recovered, the recovered high temperature hydrochloric acid is partially directly supplied to a dissolution reaction tank, the recovered hydrochloric acid is stirred in the dissolution reaction tank, and the recovered iron oxide is supplied from the upper part of the dissolution reaction tank in a molar ratio of 1.3-2.5 based on the free hydrochloric acid part of the recovered hydrochloric acid, and the recovered iron oxide is directly dissolved to the recovered hydrochloric acid to be turned into a ferric chloride solution by a reaction of the following formula (2) FeO+6HCl→2FeCl+3HO (2).
