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 tons of used boards
This pushes the gold foils off the filter and into the cup Then wait for the gold foils to settle to the bottom and get as much water out After that you could wait for the water to evaporate out and you are left with just gold However the gold foils tend to stick to the cup so I keep mine in a glass vial with some water
