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.
Here is my latest try at using milder chemicals to recover gold from computer scrap. Many thanks to deltaH and aga from sciencemadness for the help they provided with this experiment! ... You're making a lot of toxic waste, IMHO, for the gain of foils. It looks like you had up to 5 litres of cyan waste there. The more solution you …
