Abstract
A process for the electrokinetic separation of finely divided clay particles from an aqueous suspension thereof, the suspension being contained in an electrokinetic cell equipped with an anode and cathode separated by a semi-permeable membrane impermeable to clay particles. Upon activation of the cell with direct current, clay particles are caused to deposit electrophoretically on the anode. Simultaneously with the deposition of the clay deposit, portions of the water contained in the suspension and entrained in the deposit are caused to migrate electroosmotically through the membrane and collected at a cathode compartment, thereby increasing clay solids content.
