| titleOfInvention | Aluminium electrowinning cells with sloping foraminate oxygen-evolving anodes |
| abstract | A cell for the electrowinning of aluminum ( 50 ) from alumina, comprises an inclined plate-like or grid-like open anode structure ( 25 ) which has a generally v-shaped configuration in cross-section. The anode structure ( 25 ) has a downwardly-oriented sloping electrochemically active surface that is generally v-shaped in cross-section and spaced above an upwardly-oriented corresponding sloping cathode surface ( 11 ) by an anode-cathode gap ( 40 ) in which alumina dissolved in a circulating electrolyte ( 60 ) is electrolysed. The anode structure ( 25 ) has a plurality of anode through-passages ( 45 ) distributed thereover for an up-flow of alumina-depleted electrolyte ( 60 ) from the anode-cathode gap ( 40 ). One or more electrolyte guide members ( 30,30′,30 ″) located above the open anode structure ( 25 ) is/are arranged to guide substantially all the up-flowing alumina-depleted electrolyte ( 60 ) to an alumina feeding area ( 63 ), where it is enriched with alumina and then over and around an upper end ( 27 ) of the generally v-shaped plate-like or grid-like anode structure ( 25 ) into the anode-cathode gap ( 40 ). Alumina-enriched electrolyte ( 60 ) can be fed into a lower end and/or into an upper end of the anode-cathode gap ( 40 ). |
