| 摘要 |
The invention relates to a method of operating an electrolysis cell in electrowinning of metal, wherein cathode plates (1) are arranged in cathode frames (2) and the cathode plate and cathode frame are enclosed in a diaphragm bag (3) so as to form a cathode bag as- sembly, and the cathode bag assemblies and anode plates (4) are arranged in the electrolyte in an electrolysis cell (5) in an alternating and consecutive manner. A gas-sparging means (6) is disposed in each of the cathode bag assemblies, and sparging gas is supplied to the gas-sparging means (6) such that the gas-sparging means forms a curtain of fine sparging gas bubbles to flush the cathode plate (1). The cathode frame (2) comprises a gas-sparging means (6) for flushing the cathode plate (1) with a curtain of fine sparging gas bubbles inside the cathodic compartment. |
