There’s Gold in Them Thar Computers

Gold is used in many different types of electronic equipment, especially computers. With the price of gold being at an all time high, there are now numerous companies who are recovering the infinitesimally small amounts of gold. Most of the gold is found in the motherboards. 


Here’s a process of gold extraction from motherboards. This process is dangerous, therefore don’t try to reproduce it at home.

Gold is found in numerous places on a motherboard: IDE connectors, PCI Express slot, PCI, AGP, ISA, and other ports, jumper pins, the processor socket, and DIMM (SIMM on older motherboards) slots.

All of these connectors are often covered with a fine layer of gold a few microns thick, deposited by flashing or plating.

    I wish to employ the Sodium Hypochlorite/ Hydrochloric Acid leach to recover fine gold from a placer material that contains large amounts of black sand (magnetite). I have two questions:
    1. Will this process put the baser element iron into solution first, thus requiring large amounts of bleach to get the gold into solution?
    2. Is sodium metabisulphite a selective precipitant, in that it will only precipitate gold and not other metals?
    Thank you
