Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results. There are some instruments and acids involved in the process. Necessary precautions must be taken …
When it comes to electronics, gold is a highly valuable material due to its conductivity and resistance to corrosion. Some electronic …
The paper describes a small full-scale plant based on the Gold-REC 1 process, designed and patented by the University of L'Aquila; the hydrometallurgical process allows the treatment of printed circuit boards (PCBs). The first step is a mechanical treatment to reduce the size of the scraps below 2 mm. The extraction of …
Step 1: Safety Precautions: Wear your protective suit and perform the process in a fully ventilated area to avoid inhaling harmful fumes and intoxicated air. Step 2: Circuit Board Preparation: Now prepare the circuit boards that need to undergo gold removal.For this, gentle and less invasive cleaning agents will prove to be beneficial on all counts.

The best parts to use in this experiment are printed circuit boards, motherboards, central processing units, random access memory chips, drives, and other internal modems. Identify areas with gold color on these parts and strip the surrounding plastic. You should have more gold-colored components than plastic to extract a sizeable amount of gold.
Foley said it requires 5,000 litres of aqua regia to extract one kilogram of gold from printed circuit boards, none of which can be recycled. With the new U of S …
Printed circuit boards (PCBs) are a valuable source of raw materials for metal recycling considering that base metal concentration analyses have confirmed that PCB powders are multimetallic in nature and contain high concentrations of Cu, Zn, Ni, and Fe. Given that minerals are not renewable resources, these metals can be recycled …
In practice, you can easily generate those temps in a 'bucket' furnace lined with refractory, fueled with charcoal (2000 F +) It WILL stink up the neighborhood, and as I've found out through personal experience, the neighbors are going to complain :x . Fully loaded, you might be able to run a batch of 8 lbs. or so of crushed boards, and end up …
