The outlet end box 3 of a flowing mercurycathode electrolytic cell comprises a separation (brine and amalgam receiving) compartment 14 communicating with an electrolysis chamber 1 of the cell by a first gate e. g. through a slot under partition 12, and an amalgam washing compartment 13 within the separation compartment and communicating therewith by a second gate, e. g. defined by a channel 18 in the cell bottom 17 and part of the washing compartment wall 16 depending into the channel, which is disposed at an angle, preferably a right-angle, to the first gate to cause a change in flow direction. As shown brine and mercury are supplied through pipes 6, 8 in the inlet end box 2 of the cell to flow beneath partition 10 submerged in the brine, the level of which is determined by chlorine and anclyte connection pipe 11; washed amalgam leaves through outlet 19.
