There was a guy from NJ, a retired chemistry teacher or something. He put in about $8K of equipment and I forgot how many hours. When all was said and done, he said the result was a ball of gold the size of a BB pellet and a lot of haz mat issues to dispose of. He shared this experience of his to let others know that unless you are dealing with huge volume (thousands of pounds), it is just not worth it.
I forget his webpage, but I am sure I am not the only one who has looked into it and read his findings.
