Abstract
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.

A bubble collector guide capable of use in an electrowinning process, where
- the bubble collector guide comprises a plurality of guide members arranged at a distance from each other along the length of the vertical surface of an electrode, the guide members comprising a lower side, and wherein the guide members can be arranged horizontally on the vertical surface of the 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.
An electrowinning process comprising:
- using a bubble collector guide to reduce acid mist in the electrowinning process;
- further reducing acid mist in the electrowinning process beyond that reduced by the bubble collector guide.
