The invention is an apparatus and process for recovering metal from a solution. This apparatus is a structure having an anode formed from a plurality of reducing metal elements (1) and a cathode (2) formed from a high surface area electrically conductive material (5) such as metal wire. The reducing metal elements of the anode have a more negative standard state reduction potential than the metal to be recovered. This invention is also a process in which a metal is recovered by contacting a solution of a metal to be recovered with the apparatus of the invention.

Cet appareil et ce procédé sont destinés à la récupération des métaux à partir d'une solution. L'appareil est constitué d'une structure comportant une anode formée de plusieurs métaux réducteurs (1) et d'une cathode (2) formée d'un matériau électroconducteur (5) à grande aire de surface tel qu'un fil de métal. Les éléments métalliques réducteurs de l'anode ont un niveau de potentiel réducteur à l'état standard plus négatif que le métal à récupérer. Le procédé de récupération du métal consiste à mettre une solution d'un métal à récupérer en contact avec l'appareil.
