    I'm interested in this, too. I know a guy on another site that has a buyer for old cell phones, but I would love to know what to look for when I'm staring at the 'guts' of electronic equipment.

    This wasn't the exact article I was looking for, but it's not bad:

    Gold cyanidation

    Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a metallurgical technique for extracting gold from low-grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used process for gold extraction.[1] Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides.[2] Due to the highly poisonous nature of cyanide, the process is controversial and its usage is banned in a number of countries and territories

    Every other month this type of thread is posted yet after several searches I couldn't find any. Man I hate our search functionality...

    You must also legally deal with the hazardous waste that the process generates. That is VERY costly, even for the pro's. Please, leave this for professionals. Shade tree metallurgy can be dangerous and costly. Just my honest two cents. DYODD.

    Ask Mr Shiny if you doubt me.

    I've bought from this company before, but not their gold recovery systems. They sell some interesting stuff.

    might be better off accumulating the old electronics for free/cheap, then selling them in bulk to someone that already does it, then turn the cash to pms?
