Did you know that your computer has a gold metal?

Yes, gold is also used in computers, even if only by a few that he exists, and is used especially in the gold connectors (pins) processors, RAM, but also in some other conductors ... -

 The first versions of old computers are available on a very large amount of gold because she was the sole and exclusive material that is used by reducing the increase in modern processors, as well as some spare computer. Thus, there are many companies are recycling these computers for extracting gold from these pieces.

 If you search in Internet you will find a range of forums and websites talking about how recycling (recyclage) Computer cut for the extraction of gold, as you'll find many threads talking about treatments that are available to a large proportion of gold.

 And processors that are available on a significant proportion of gold processors are:
Intel 186/286/386/486 / Pentium / Pentium Pro / i860 / i960

Cyrix 486/586 / MII
IBM 486/586/686
Motorola 68000/88000 series
NEC & Toshiba MIPS series: R4000 / R8000 / R10000 / R12000
AMD 286/386/486 / K5 / 29000 series
IDT Winchip C6 / 2A
DEC Alpha
HP PA-7000 & PA-8000 RISC series
SUN SPARC / UltraSPARC / SuperSPARC RISC series

 As for modern processors such as the Pentium 4 was only available at low rates of gold as with the evolution of technology has become this article are blended materials CHEMICAL other in order to have the same cost-effectiveness, however, that this does not prevent in cases where a very large number of these processors and RAM and other that is the extraction ratios of gold metal.
The method of extracting gold from these pieces is expensive compared with the amount of gold extracted this leaves it to companies that competent in this area, but this does not prevent the existence of explanations on YouTube, for example, show how you can extracting gold from processors or RAM like this video below.
