Hello friends,
Seniors & Masters,
I am working with 200 cell phone boards,
I have depopuleted with heat gun,
After that I have given the HCL bath,
Now The cell phone board is almost free from tin and solder and I am going to AP process,
I am having the chemical with below parameters,
Hydrochloric Acid 35%
Hydrogen Peroxide 30%
Nitric Acid AR,69-72%
Sodium Disulfite
=> For AP process How much I have to use Hydrochloric Acid 35% and Hydrogen Peroxide 30%
- Please give me the measurement,
=> For AR process How much I have to use Hydrochloric Acid 35% and Nitric Acid AR,69-72%
- Please give me the measurement,
=> And at last Can I use Sodium Disulfite to get Gold Powder from Au solution ?
-If yes then - Please give me the measurement,
This is my first experiment,
So Please help me
