Hey guys,
This is my first post so excuse any mistakes thanks.
So I had 500grams of intel pentium pro processors so about 10 chips,
I usually dealt with p1 ceramic CPUs I recovered about 2.5grams of gold
from 1kg of those and did that about 3 times successfully.
But with this I messed up somewhere... Here's exactly what I did.
I headed the chips and took the bottom lid off. I didn't break any of the chips
I soaked that in 500ml of HCL 36% and added about 100ml of water.
Than I headed the solution in a bath of boiling water with continues heat.
Than added NaNo3 (sodium nitrate) one teaspoon every 10 minutes. ( I usually decrease the sodium
Nitrate by 1/2 every time I add it but this has more gold than I'm usto so I did 2 full spoons than 2 halfs) heated it for about an hour than I let it cool to room temperature fitiltered the solution than added about 7 ice cubes and 50 ml of sulfuric acid by drop than let it sit for an hour and half than I filtered the silver and lead that precipitated now I had this solution that had gold left in it so I added 2 teaspoons of UREA to neutralize the nitric acid.. Than added a teaspoon of SMB it fizzed a bit and a little red between the fizz but only if I add alot to one spot but it did fizz.. So I let it sit the night... And nothing in the morning it looked exactly the same.. I checked it with Stanous chloride ( I check it by mixing the tin2chloride power with water and putting a drop of the mixture on a tissue and than added a drop of the solution) the tissue darkened a bit.. But I think that's because there is alot of the solution... So I read a few forms and read that a sodium hydroxide solution dropped in will help the gold drop.. So I tried it and every drop that went I. The solution turned completely black and floated on top I added about 100ml of that the form said 50ml but I had 500ml of hcl to begin with So I thought it would be right to double the amount..
But when I stir the soulition it just dissolves.. Please help and thank you in advance to who ever took the time to read this...
