Hello everyone,
Firstly, I would like to introduce myself, I'm Evrim, 19 years old born and raised in Holland . I want to start soon with recovering golds from CPU pins, I did a investigation for how can I do this work, so it will be my first time. Therefore you will make me very happy if you can give some short advices about this work. I have some questions in my mind, really it will be good if you can help me. As some questions that I will ask you:
- How many milliliters should I use for Hydrogen Peroxide (3%) and Muriatic Acid 20 Be (31%)? Can we understand with 3:1 ratio that it is 300 ml Muriatic acid and 100 ml Hydrogen acid/ peroxide?
- Is it required to use Hot plate after adding the pins to the flask? If so, how long will I have to wait with hot plate? What can I later do with flask on hot plate when it’s finished with waiting?
- What type of water should I use for a wash bottle? Can I use tap water?
- Is Urea needed for neutralize the remaining nitric acid? If so, how much should I add Urea in the flask?
Please forgive me if I did bother you.
Thanks so much in advance.
