ABSTRACT A reusable cartridge for extracting precious metal from solutions containing such metal by means of a replacement reaction is disclosed. A dispersion means distributes incoming solution uniformly through a cylindrical housing having a spiral rolled exchange mass therein. The mass contains fine particles of replacement metal of higher electromotive force than the metal to be recovered. Spacer rings are provided to secure the spiral mass in position, to aid in directing the flow of solutions uniformly through the exchange mass and to prevent overly large flow paths from developing between spiral layers. A removable outlet end cap allows access to the interior of the cartridge for removal and replacement of the exchange mass thereby making the cartridge readily reusable.
