Abstract

The pulverised solids are in the form of a suspension in an electrophoresis and electroosmosis cell; the process is characterised in that a fraction of the catholyte (13) is removed and then treated (15), part of it being treated with an acidic, preferably gaseous, agent (19), the treated part being reintroduced into the cathode compartment (14) while the other part (18) of the fraction removed is eliminated (17, 18). The acidic treatment (19) is servo-controlled by the continuous measurement of the pH (20) of the fraction removed from the catholyte (13). <IMAGE>
