Extract gold from motherboards

Today you will learn how to get the gold out of old motherboards with their own hands. Please note: chemicals that are used in the demonstration, very dangerous, especially when combined concentrations. Therefore we do not recommend repeating this experiment at home.






Gold is present in many elements of the motherboard: connectors IDE, slots, PCI Express, PCI, AGP, ISA, and other ports, bridges, in the CPU socket and slots DIMM (SIMM on older motherboards). All these connectors are often coated with a thin layer of gold in a thickness of several microns.

The first stage of our experiment is to remove all of these contacts and connectors. We will need wire cutters, pliers and cutters, flat and Phillips screwdrivers, as well as a certain amount of time.



For the experiments need a large number of contacts - they just gave our "donor" motherboards.



We also need chemicals and tools.
