Title:
ELECTROLYSIS CELL
Document Type and Number:
WIPO Patent Application WO2001096628
Kind Code:
A3
Abstract:
An electrolysis cell for recovery of a metal by electrolysis from a molten electrolyte containing a metal compound, wherein the molten metal has a density lower than the molten electrolyte and the compound produces a gas during electrolysis that reacts on contact with the molten metal. The cell has a housing (H) containing a number of electrode assemblies (11), (14), (12) each of which is provided with a hood (35) enclosing an upper portion of the electrode assembly including the cathode (12) of the assembly. The hood in operation provides a gas collection chamber such that the gas generated by each electrode assembly is isolated from other electrode assemblies and from metal collecting in the housing outside each hood.
