Abstract
A process for the manufacture of an aqueous solution of ferric chloride including the steps of introducing an aqueous solution of hydrochloric acid into a reactor containing a bed of fragments of an oxide-containing iron ore so that the aqueous solution of hydrochloric acid travels upwardly through the bed, collecting a suspension of ore particles in an aqueous solution of ferric chloride from the bed mechanically separating the ore particles from the aqueous solution of ferric chloride of the suspension, and recycling the ore particles by adding the ore particles to the aqueous solution of hydrochloric acid upstream of the bed.
