Abstract
An electrolysis cell for producing metals by electrolytic reduction of molten baths which includes non-consumable inert anodes and refractory hard metal cathode elements. The cathode elements are replaceably mounted in the electrolysis cell and have inclined planar working surfaces which have grooves therein. A method for producing metals by use of the electrolysis cell includes utilizing the grooves to control the release of anode gases.
