So it took a while but I am getting there. The solution was too saturated so I refreshed it with 500ml HCl and turned on the bubbling again.
There was still about 5% gold pins on the fingers.
I rinsed it for the first time and this is the result. What a great sight to see for the first time.

I collected the HCl with Copper to get the clean in a later stage.
Then I rinsed the filter with plenty of water and collected that in a separate flask.
It is light blue. Can I neutralize it and drain in through the sink or is there too much metal in there?
