Found this from "Instructables".....and found it interesting.
Maybe not too practical....unless you live in a 3 world country......

Thought the use of Borax instead of mercury...was interesting as well.
After I finished high school....left town.
Returned to find that a friend....kinda a pre computer nerd ....had started a business recovering silver from x-ray and other industrial processes....and making a good buck at it.
Who would have though it.....?
