Magnetic Pins?

[lazersteve]

AP is quite interesting thing. I dissolved all gold in AP. I made AP vith 50% peroxide. I tryed to put this thing quite few but result was that ewerything was dissolved. Next time I try 3% peroxide. In my coutry cost 50% peroxide 5 time less than medic grade from store. This was reason why I used so strong peroxide.

Buy the cheap stuff and dilute it for the reaction before adding it to the acid.

I bought a cheap stuff. :lol: 35Kg 60% nitric, 35 Kg 33% muriatic and 22Kg 50% peroxide was cost only 140$. But medic grade or laboratory stuff is abot 20 time expenssive. But yeah I dilute this stuff next time. At the moment I have a little bit more work to get gold from this AP.

to make 1l of 3% H2O2 out from 50% grade you need to mix 940ml of water with 60ml 50% h2o2 according to this dilution calculator:

Put them in the AP and process them.

what if they are magnetic pins? what then? thanks. alan

If the pins are magnetic put them in some HCL in a crock pot and let them run.

what about cpu pins with some solder still included. could i process them directly in AP or should I treat them with HCL first to remove the solder? thanks.

what's the reason being and for how long? thanks for your quick response. much appreciated. alan

The pins being magnetic indicates they are steel and I just run the ones like that in HCL in a crock pot. The heat speeds up the reaction.
