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.
a question, does it worth? the gold can afford the cost of the chemicals and leave a gaining?
but would cost more than it makes if you dont already have the stuff??
That means I do the complete opposite!!
By the way, professionals do filtration of concentrated acids with filters made from sintered glass, not paper filters. But then you need a vacuum pump and other equipment to do it appropriate.
Not very clever to start a process without adequate equipment.
And all of you people who think it is not worth your time... your right its not you would probably just hurt yourself anyways. So keep throwing away your old electronics I'm sure someone is thanking you for it.
@or not: not everything is sold on ebay you effin nerd get outside and explore.
