How to precipitate gold from Hydrogen Peroxide?

Hi
I have a problem with H202. I have dissolved copper and gold in H202 dropping the copper is easy enough but I was wondering if anyone had any ideas on on getting the gold out of it.

I have several gallons of this stuff and hate to see it go to waste, any suggestions?

How do you dissolve gold in peroxide? Some will drop out if you kill the peroxide. Sugar will do that. Boil it down is another way. Be careful of this as peroxide reaches a temperature where it generates so much heat that the reaction becomes faster and faster yielding bubbles all over the place. vacuum evaporation will work if you have a vacuum source. Slow but safe. There are a couple of organic compounds that will drop out gold as a sponge. Have not seen it in print in a couple of years tho.
