The invention discloses a metallic electrolytic cell which comprises a cell body, anode plates, cathode plates and arc-shaped drainage bulges, wherein the arc-shaped drainage bulges are mounted at the two opposite ends of the cell body; the anode plates and the cathode plates are alternatively arranged in the cell body, and liquid inlets and overflow openings are formed in the cell body; the liquid inlets in the two sides of each cathode plate are positioned in the same end of the cathode plate, and the liquid inlets in the two sides of each anode plate are respectively positioned in the two ends of the anode plate; the two ends of each cathode plate are respectively butted with the convex ends of the arc-shaped drainage bulges, and a liquid drainage cavity is formed between the cathode plates and the arc-shaped drainage bulges. Two adjacent cathode plates and one anode plate between the cathode plates form a similar closed space, electrolyte is fast ejected to enter the space through the liquid inlets in one end of one cathode plate and the other end of the adjacent cathode plate, and then the electrolyte flows clockwise and anticlockwise. The kinetic energy of electrolyte is utilized, the concentration difference of metal ions between the two pole plates is greatly reduced, and the concentration polarization is effectively reduced. The invention further discloses a metal electrolysis process.
