vietnamese gold deposit desorption electrolysis system use

desorption electrolysis system - xinhaiepc.com

in gold electrowinning process,when the electrolysis equipment is added with anions which 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 is process via ionization. at last, solid gold is attained.

- the high temperature and high-pressure desorption method is to install the gold-loaded carbon in a pressure vessel, and mix the solution with 0.4% to 1% naoh and 0.1% nacn, heat temperature to 130 to 160 ° c, under the pressure of 3.6 to 5.9 kg/cm2. within 2 to 6 hours, the gold and silver desorption rates of gold-loaded carbon exceeded 90%.
