ABSTRACT:
A method for the cementation of a metal from a solution containing metallic ions by the addition of a finely divided cementation medium, wherein the cementation reaction is carried out in a reaction chamber located in an oscillating reactor which is at least partially filled with agitation bodies inert with respect to the reaction, the agitation bodies having a maximum dimension in the range from 2 to 150 mm and being sufficiently large to transmit the oscillations of the reactor into the reaction chamber, the specific gravity of the bodies being appreciably greater than the specific gravity of the solids in the reactor. The method is particularly applicable to the cementation of copper.
