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