Abstract
The utility model discloses a columnar membrane electrolytic tank for electrolyzing gold from cyanided pregnant solution, which consists of a tank body, a cathode, an anode and a cation exchange membrane. The tank body is cylindrical; and the cathode, the anode and the cation exchange membrane are arranged in the tank body. An electrolysis unit is divided into two chambers by the cation exchange membrane, wherein an inner chamber is a cathode chamber, and an outer chamber is an anode chamber. A cyanided pregnant solution inlet is formed at the top of the tank body. An electrolysis residual liquid outlet is formed at the bottom of the tank body. An anolyte outlet is formed on the lower sidewall of the tank body. An anolyte inlet is formed on the upper sidewall of the tank body. The columnar membrane electrolytic tank achieves high anodic current efficiency, eliminates the phenomena of damage of CN<-> and mechanical mixing of products, and improves the electrolysis level of the gold (Au(CN)<->) of the cyanided pregnant solution.
