Summary of Mercury Amalgamation Gold

04.01.2020ยท The principle of gold extraction by using mercury (amalgamation method) is mainly that after the mercury is added to the slurry, the surface of the gold particles is wetted by mercury, and then the mercury diffuses into the interior of the gold particles, causing a chemical reaction. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form.

But the aquaregia solution method of extraction can be easily automated for precise and faster extraction. The intension of our paper is to propose an idea of an automation system for the recovery of gold from E-waste. This system for gold recovery is solely controlled by the microcontroller. There is use of several types of sensors, which are in turn act as input providers to the
