Electric endosmose.-In an electro-osmotic process for eliminating water from paste or mud of mineral, vegetable, or animal substances, the various solids are deposited fractionally in accordance with their different natures or physical properties, and are thus separated from one another. In one method of carrying out the process, the suspension is contained in a metallic vessel which serves as the electrode towards which the water wanders, say, the cathode ; the other electrode is immersed in the mixture and may be surrounded by a pervious partition. The finest particles first deposit at the anode or at the surrounding partition, the process is then interrupted, these deposited particles are removed, and coarser particles are then deposited, and so on. In another method the mixture is caused to pass through a series of apparatus so arranged that the finest particles are deposited in the first vessel, coarser particles in the next, and so on. When thick mixtures are under treatment, the process is carried out in a vessel of non-conducting material ; the anode is arranged as described above, while the cathode consists of wire netting or perforated sheet metal and surrounds the anode ; the solid particles outside the cathode on their way to the anode then pass through the cathode, that is, through a zone containing few particles in suspension and are thus more readily separated ; the mixture outside the cathode is by preference stirred during the process.
