Abstract

1. Process for the electrolysis of an aqueous alkali metal halide solution in an electrolysis cell of which the cathode is a sheet of mercury (11) flowing on an inclined baseplate (5) of the cell, in which the baseplate is caused to vibrate, characterized in that distinct zones (27, 28, 29, 30, ... 31, 32, 33) of the baseplate (5) are caused to vibrate separately and successively from the downstream end to the upstream end of the sheet of mercury (11), and the vibrations applied to each of the said distinct zones are controlled.
