If you have access to a large amount of e-waste, you may literally be sitting on a gold mine. There is gold that can be recovered from discarded computer circuit boards--but in such small amounts that the time-consuming and dangerous process required to remove gold from computer circuits is only worth your while if you have at least 1.5 tons of used boards.

I''ve been extracting and collecting the balls from old style computer mice for a few years and have hundreds now. The rubber coating usually comes off without too much trouble--simply cut around the circumference and remove. They would make great media for a ball grinder. I also now realize that I have a small ball mill.

Many years ago, particle size reduction was done by gravity stamps and years later, was common to employ crushers such as jaw or cone crushers, and ball mills to reduce to whatever mesh is desired. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10-11.
