Process of continuously separating electrically charged, solid pulverulent materials in the form of a suspension in an electrophoresis and electroosmosis cell, characterized in that a fraction of the catholyte is drained off, that a portion thereof is treated with an acid, preferably gaseous, agent, that the treated portion is re-introduced into the cathode compartment, whereas the other part of the drained-off fraction is eliminated. The acid treatment is effected during continous pH measurements on the drained-off fraction of the catholyte.
