摘要 |
<p>A cathode bottom of a cell for the electrowinning of aluminium from alumina comprises a horizontal aluminium-wettable drained cathode surface having a series of parallel spaced apart recessed grooves extending across the cathode bottom for facilitating collection of product aluminium draining from the horizontal cathode surface. The cathode bottom comprises a series of cathode blocks placed side-by-side along the cathode bottom. Each cathode block extends lengthwise across the cathode bottom. The cathode blocks have flat top surfaces that form said horizontal aluminium-wettable drained cathode surface and cut-outs or bevels along opposite upper side edges that extend across the cathode bottom so that two cathode blocks placed side-by-side along their cut-outs or bevels form between them one of these recessed grooves across the cathode bottom. <IMAGE></p> |
