摘要： A hydroelectrometallurgy method comprising suspending particles of a crude metal or metal sulfide in the anode zone and seed particles of pure metal in the cathode zone, causing such particles to collide with the surfaces of the anode and cathode, respectively, and thereby effecting the corresponding electrochemical reaction on each of the particles, whereby metal ions are formed in the anode zone and the seed particles grow into coarse particles in the cathode zone as the result of precipitation of the metal thereon. According to this method, since the total surface area of the particle is very large, a greater electric current can be applied as compared with the conventional electrolytical refining or winning method, and the manufacturing rate of pure metal can be increased greatly.
