Electrode for electrorefining

An electrode for use in electrowinning or electrorefining metals, comprising an electronically conductive block having an upright, generally planar face, the face having formed therein a network of interconnecting channels, the channels being disposed to provide a plurality of continuous routes for molten metal to flow overall downwardly across said face, said routes comprising a plurality of downward channels fluidly coupled to a single horizontal distribution-and-mixing channel fluidly coupled to at least one further downward channel so that the routes are interconnected by the horizontal channel, thereby promoting mixing and break-up of liquid streams flowing therethrough.
