Electrowinning Cells - Kemix
In cyanide solutions, gold is present as a stable auro-cyanide complex anion with a relatively high cathodic potential (E0). The cathodic shift demands a higher cell voltage and consequently other cathodic reactions like the formation of H2 and the reduction of O2 can also occur. These additional reactions consume current and reduce the current efficiency of the gold electrowinning process ...
