Making an honest dollar.

Gold is a soft metal easily worn free by abrasion in a tumbler, the brown powder along with some copper that also found its way into the mix.

The copper gold mix in the flower pot, copper is removed via a DC electric current, copper is plated onto the copper sheet. after a couple of days the copper is nearly completely removed, the electrolyte now saturated with the brown gold powder. The remaining copper chemically removed.

I now have 65 grams of gold powder to further refine,

Another day another dollar.

If the visitors have nothing to say, neither do I

Um gross.so how many of those grams do you think will be gold in the end ? What purity do you get from that I wonder also how much money do you spend on such a process is it costly?.

It's amazing how resourceful people can be. Some folks don't have much but they make the most of what they do have to work with.

I was just playing around awhile back and experimented with depopulating the boards. Had an old 4" planer / jointer that wasn't being used anymore and tinkered with planing the back side of the boards. That seemed to work pretty well.

If you can imagine .... anything that poked through the board and was soldered on the back .... was effectively de-soldered. A few taps on the board and everything falls out.

I was thinking that a milling machine would give you real good accuracy for board shaving purposes.

When you think about it .... just about everything on the board has value. Even the copper foil laminate traces would add up some weight pretty quick.There's value in the solder and there must be a fair amount of nickel too. It might be that the best money would be in the base metals and PM's the frosting on the cake. I've heard a figure of $ 20,000.00 / ton of recovered metals from circuit boards going to refiners that have a really good process.
