How do recycling businesses make money on old electronics?

Question

How is this done?

Answer 1

THEIR ARE CERTAIN TYPES OF METALS IN EACH COMPUTERS THAT ARE WORTH MORE N MONEY THAN THE COMPUTERS THEMSELVES, COMPUTERS COULD'NT RUN WITHOUT THEM, BUT IF YOU WERE TO GET SAY 25 OLD COMPUTERS AND SEPERATE THE METALS FROM EACH AND KEEP EACH TYPE OF METAL TOGETHER, YOU WOULD BE ABLE TO GET RICH QUICK.

Answer 2

First you have to remove the parts that contain the precius metals you are looking for such as fingers cpu s etc then you would use an acid (such as nitric, aqua regia, hydrchloric, even sulfuric ) to digest the base metals, leaving you with your metals of value such as gold.  This is a very breif description, and this process is very dangerous, some of the fumes created are extremely deadly.  Don't try this at home.   for more info visit  www.goldrefiningforum.com
