Membrane electrolyzer for gold electrowinning from cyanidation pregnant solution

This utility model disclosed a membrane electrolyzer for gold electrowinning from cyanidation pregnant solution, which is consisted of the cell, the cathode frame, the anode plate, and the cation exchange membrane. There are three chambers in the cell unit, the two ends are cathode chambers, and the middle is the anode chamber. The cathode chambers and the anode chamber are separated by the cation exchange membrane. This utility model has higher anodic current efficiency, eliminating disruption of CN- and the phenomenon of product’s mechanical mixture, which improves the electrowinning effect of gold (Au（CN）2-) from cyanidation pregnant solution.
