Sloshing loads of Peroxide in will do that for sure Dark. As mentioned before, an initial small amount is a useful catalyst to get things moving.

Help Support Gold Refining Forum:
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?

Nice.
Just set the AP solution aside and use next time.
It lives practically for ever.
What about the light blue solution which contains mainly of water with a little bit of left over copper solution?
Can I dispose of that through the drain after it is neutralized or is there too much metal still in it?
Keep the solution and reuse it for rinsing the next batch of chips . Why create more waste right .
Put it with the rest of your liquid waste and run it through a proper waste treatment.
The AP is not waste.
When I was told by a member, that CuCl2 can practically be used. Over and over...I was like really. Then he said, throw you some pins in the bucket, just forget about them. For week or two. Again, I was like really. Well , great advice...listen to what these people are telling you. They know their gold recovery/ refining. Thanks again Shark. And remember once you get a well established bucket of CuCl2. You don't have to use peroxide no more. Maybe add a little, fresh, Hcl to it.
If the only base metal being dissolved is copper, the solution is, indeed, reusable over and over. But it's the other metals that may go into solution that can eventually cause it to lose its usefulness. Pins, for example, are not pure copper as the base metal. The most common is probably brass, a mixture of copper and zinc. Eventually, the zinc will cause all the copper to cement out, and a zinc chloride solution is no longer an effective leach. I'm not saying not to use it for pins. Just be aware that over time, it will become less effective.
