Working Principle

Page view:

At the temperature of 150℃, rinse gold-loaded carbon with NaOH solution at 5% concentration in the elution column. The solution carries gold ion from gold-loaded carbon and forms eluate. The eluate is then released into a electronic-winning cell, where the gold ions obtain electrons, form gold atoms, gather onto the cathode plate and finally produce gold powder (gold slime).
