A removable electrode module for engagement with an electrolysis chamber comprises a first electrode, a second electrode, and a suspension structure. The suspension structure comprises a suspension rod coupled to the first electrode. The second electrode is suspended or supported by the suspension structure, which comprises at least one electrically-insulating spacer element for retaining the second electrode in spatial separation from the first electrode.

Electrolysis apparatus

In a method for reduction of a solid feedstock, such as a solid metal compound, in an electrolytic apparatus a portion of the feedstock is arranged in each of two or more electrolytic cells (). A molten salt is provided as an electrolyte in each cell. The molten salt is circulated from a molten salt reservoir () such that salt flows through each of the cells. Feedstock is reduced in each cell by applying a potential across electrodes in each cell, the potential being sufficient to cause reduction of the feedstock. The invention also provides an apparatus for implementing the method.

Apparatus and method for reduction of a solid feedstock

In a method for reducing a solid feedstock (), such as a solid metal compound, feedstock is arranged on upper surfaces of elements () in a bipolar cell stack contained within a housing (). A molten salt electrolyte is circulated through the housing so that it contacts the elements of the bipolar stack and the feedstock. A potential is applied to terminal electrodes () of the bipolar stack such that the upper surfaces of the elements become cathodic and the lower surfaces of the elements become anodic. The applied potential is sufficient to cause reduction of the feedstock. The invention also provides an apparatus for implementing the method.
