<p>Process and apparatus for the manufacture of aqueous solutions of ferric chloride, in which an aqueous solution of hydrochloric acid (6) undergoes a rising movement through a bed of fragments of an oxidised iron ore in a reactor (1), a suspension (7) of particles of the ore in an aqueous solution of ferric chloride is collected from the bed, the suspension is treated (8, 10) in order to extract the particles therefrom, the particles (11, 12) and the ferric chloride solution (14) are collected separately and the particles are recycled in the aqueous solution of hydrochloric acid (6).
