THE METHOD OF OPERATING A HORIZONTAL-TYPE, FLOWING MERCURY CATHODE ELECTROLYSIS CELL, HAVING A STATIONARY BASE, AND INCLINED TOP, ANODES AND A FLOWING MERCURY CATHODE WITH AN ELECTROLYTE GAP AND NO DIAPHRAGM BETWEEN THE ANODES AND THE CATHODE, SAID BASE, TOP AND ANODES BEING SPACED FROM EACH OTHER WITH THE BASE AND ANODES SUBSTANTIALLY PARALLEL WITH EACH OTHER WHICH COMPRISES MAINTAINING THE CELL BASE AT AN INCLINATION OF BETWEEN ABOUT 2* AND ABOUT 85* FROM THE HORIZONTAL, MAINTAINING THE ELECTROLYTE GAP BETWEEN 0.12 AND 0.04 INCH, FLOWING A MERCURY FILM A THICKNESS OF BELOW .62 INCH BY GRAVITY OVER THE BASE OF SAID CELL, FLOWING AN ELECTROLYTE THROUGH SAID CELL BETWEEN THE ANODES AND THE FLOWING MERCURY CATHODE, FILLING THE CELL WITH ELECTROLYTE SOLUTION TO THE TOP THEREOF, PROVIDING A GAS SEPARATING SPACE AT THE UPPER EDGE OF THE INCLINED CELL WHERE THE TOP AND END WALL INTERSECT AND PASSING AN ELECTRIC CURRENT THROUGH THE ELECTROLYTE BETWEEN SAID ANODES AND SAID FLOWING MERCURY CATHODE, TO DISSOCIATE SAID ELECTROLYTE INTO ANODE AND CATHODE PRODUCTS, RECOVERING THE CATHODE PRODUCT IN THE FLOWING MERCURY CATHODE AND RECOVERING THE ANODE PRODUCT ABOVE THE ELECTROLYTE LEVEL OF SAID CELL.
