    摘要: An apparatus for use in extracting primary zinc metal from ore concentrates is described. The apparatus includes first and second electrolytic cells, the first cell receiving an acid zinc sulfate solution derived from an ore concentrate, and having an anode which is insoluble in said solution, and the second cell containing an alkaline electrolyte and having a cathode which is insoluble in said electrolyte. A common electrode is also provided which is insoluble both in the acid zinc sulfate solution and in the alkaline electrolyte. The common electrode can be transferred between the first cell, in which it acts as a cathode, and the second cell, in which it acts as an anode. The zinc sulfate solution is subjected to electrolysis in the first cell with the common electrode acting as a cathode, thereby causing primary zinc metal to be deposited as a coating on the common electrode. The coated common electrode is transferred from the first cell to the second cell and the alkaline electrolyte in the second cell is subjected to electrolysis so that the primary zinc metal is transferred from the common electrode to the cathode of the second cell in a sponge-like form. The zinc sponge is mechanically removed from the cathode of the second cell.

    摘要: An apparatus used in the electrodeposition coating of a continuous sheet of metal as it travels in a horizontal pathway between a pair of electrically charged electrodes and through a bath of liquid coating solution that is continuously circulated to the bath through a pair of liquid seals which are disposed adjacent opposing, aligned openings through which the sheet of metal enters and exits a chamber containing the bath. The liquid seals are each comprised of a pair of nozzles for directing converging streams of liquid coating solution against the traveling sheet of metal in the direction of the chamber and have a three-fold purpose. They are designed to, (I) prevent the escape of liquid coating solution from the chamber through the openings, (II) provide a liquid support for the sheet of metal at the openings in the opposing end walls of the chamber, and (III) direct fresh liquid coating solution along the sheet of metal into the critical area or space between the electrodes to maintain and keep uniform in this area, the concentration of the liquid coating solution that becomes diluted as the coating material of the solution adheres to the sheet of metal during its travel between the electrodes. A pair of blow off nozzles are supplied adjacent and outside each of the liquid seals to direct air, under pressure, angularly against the sheet of metal in the direction of the chamber to aid in the prevention of the escape of liquid coating solution from the apparatus, to provide an additional fluid bed for supporting the sheet of metal and to minimize and control the thin film of liquid coating material which adheres by surface tension to the sheet of metal.

    摘要: A tank is provided in which a lower solution is covered by an upper solution which is non-miscible with the lower solution. In the operating condition the apparatus automatically uncovers a small area of lower solution by raising the level of lower solution in that area and having the upper solution pass over a weir into a holding chamber. When the operating condition ceases, the solution automatically returns to the same levels as in the static condition.
