The invention concerns a bubble collector guide for use in an electrolysis process, which comprises a plurality of guide members arranged at a distance from each other, the guide members comprising a lower side. The guide members can be arranged horizontally on the vertical surface of an electrode so that the lower side of the guide member forms a downwards facing surface that is substantially orthogonal to the vertical surface of the electrode, so as to collect bubbles of gas generated at the electrode.

Bubble collector guide and use thereof

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