Sistema de conductos de gas, equipo que lo comprende y metodo para la recuperacion electrolitica de metales, dicho sistema esta en conexión con medios que llevan gas al sistema, mediante el cual hay un numero apropiado de agujeros de suministro de gas en el sistema de conductos de gas en una pared que limita dicho sistema.

摘要

The invention concerns a system of gas ducts (6) for transporting gas, for example, into electrolytic equipment, in connection with which there are means (13) for taking at least gas into the system of gas ducts, whereby there is a suitable number of gas supply holes (7) in the system of gas ducts in a wall (19) limiting the system of gas ducts, whereby the material, such as gas, flowing in the system of gas ducts (6) is prevented at least in part from passing through the wall (19) of the system of gas ducts (6). The invention also concerns equipment and a method for electrolytic recovery of metal, such as copper.
