I have approximately 1kg of PC2 RAM with IC Chips embedded on both sides.
I sliced gold fingers and separated IC Chips.
I created Aqua Regia with 375ml of Hydrochloric Acid. and 125ml of Nitric Acid for melting the gold fingers.
A day after, I filtered the Aqua Regia and added around 20g of smb. I added 20g of smb because all the videos I referred to
added a few spoonful of smb during their gold recovery processes.
After further researching about the amount of smb I should add, I found out that in order to recovery 2g of gold out of it, I should only add 1g of smb.
I am a bit confused now. Exactly how much of smb should I add during the process?
I would appreciate your help a lot.
Thank you.
