An apparatus for recovering a metal from a toxic solution is disclosed. The
apparatus includes a plurality of vessels (10, 10a, 10b) for containing the
solution, each vessel (10) including an upper portion above the solution,
electrode (50) extending into the solution in each vessel (10) for passing an
electric current therethrough wherein toxic mist occurs in the upper portions
of the vessels (10, 10a, 10b) above the surfaces of the solution, at least one
pair of said vessels (10-10a and 10-10b) being disposed in a side-by-side
relation to define spaces (44, 46) therebetween, and creating an airflow in
the upper portion of the adjacent vessels from the space (44) between one pair
of vessels (10-10a) to the space (46) between another pair of vessels (10-10b)
for evacuating the toxic mist from above the solution in said vessels (10,
10a, 10b).
Appareil servant à récupérer un métal contenu dans une solution toxique. L'appareil comporte plusieurs cuves (10, 10a, 10b) destinées à contenir la solution, chaque cuve (10) comprenant une partie supérieure située au-dessus de la solution, une électrode (50) traversant la solution dans chaque cuve (10) pour y faire passer un courant électrique ceci produisant des embruns toxiques dans les parties supérieures des cuves (10, 10a, 10b) au-dessus des surfaces de la solution, au moins deux desdites cuves (10-10a et 10-10b) étant placées l'une à côté de l'autre pour définir des espaces (44, 46) entre ces dernières et pour créer un écoulement d'air dans la partie supérieure des cuves adjacentes depuis l'espace (44) existant entre les deux cuves (10-10a) jusqu'à l'espace (46) existant entre les deux autres cuves (10-10b) afin d'évacuer les embruns toxiques présents au-dessus de la solution située dans lesdites cuves (10, 10a, 10b).
