grind up the circuit board and melt the board. it will stink so go outside
Green, Red, Purple, Gold, Blue are all used.
electrical connections and circuit boards. gold conducts electricity very efficiently and does not corrode.
It was once used in all the circuit boards such as the motherboard. However this was expensive, and it's rare to find any gold in modern computer electronics.
To melt gold off a printed circuit board (PCB), use a furnace or a torch to heat the PCB until the gold components reach their melting point. The molten gold can then be collected and separated from the remaining material in the PCB to extract and refine the gold. Remember to take necessary safety precautions when working with high temperatures.
firstly, Only on Certain circuit boards. secondly, gold is a malleable, non-corroding/rusting conductive metal. gold has the lowest resistance to the flow of electricity through it; this side of a superconductor.
The only gold you may find in a digital camera are small slivers of gold used to establish internal surface mount wire connections on the pc boards. Probably nothing worth taking it apart to salvage for. TVs are known for having gold in PLASMA tvs in some of their circuit boards as well.
For gold extraction out of electronic equipment in circuit boards
for one thousand pounds of circuit boards you can expect at today's rates to get ~$10,000 after it is refined
Not much, since the gold is typically just a thin plate over copper traces. Printed circuit gold is usually only one or two mils thick and you'd need several boards to make up an ounce of gold. It IS worth it, but you'd need to process several boards to make it worth your time and effort.
== == No, you do not 'grind' up the circuit boards containing the gold. You remove the 'ears' and other parts that are plated with gold. You have a few options as to the heating of the gold, which will not be pure and needs to be separated out from the impurities. The best method without producing hazardous waste is with a Shor refiner. They are expensive. There are other 'dry' methods of extracting the gold using various heating methods, some of which are advertised on Ebay. Either way, if you are burning ANY electronic circuit board, you are producing noxious fumes and this needs to be done outdoors, period. As for the power cord being 'worth' more than the gold in the computer, that's just bullcrap. The older 286, 386 and 486 chips, have much more gold plating on them. With gold holding at $900 per oz, I'm thinking of getting into the refining business.

An AARL (Anglo American Research Laboratories) strip circuit is a method used in gold processing to extract gold from a solution. The circuit involves a series of process steps including adsorption, desorption, and electrowinning to separate gold from other metals.
