Desorption And Electrowinning Used In Gold Mining Cil

In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au(CN)2-is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.

Gold recovery by electrowinning & reducing copper content

I think the better way is carbon adsorption of pregnant liquids before electrowinning,by simple activated carbon in column CIC. So you can concentrate gold and copper into the activated carbon, then you can easily make two stages of desorption, first with cold cyanide solution for copper recovery, and then with other hot cyanide desorption
