Okay I have started reading the book and already find it I testing
I meant Urea

Worse, it do not fully decompose the Nitric compounds, and...I meant Urea
I haven't been too activeWorse, it do not fully decompose the Nitric compounds, and...
Urea can create explosive compounds when in contact with Nitrates.
Use Urea for what it is, a fertilizer.
For deNOxing you use Sulfamic acid in a hot solution.
But do what I told you, set your stuff away in a safe place and study the book and the sections I recommended.
Have you studied the forum at all...?
You have been doing everything wrong, so what have you been doing since you became a member?
Drop youtube completely (its a potential killer in this respect) and if you absolutely NEED to use Youtube, watch Sreetips, Owltech, and a couple other members, they make good and safe videos.

Welcome to us.I am having some issues with my precipitation of gold.
I had about 1kg of IC chips which i ashed and used nitric to remove the base metals.
Then I filtered the nitric solution in another beaker and washed the chips with water so as to remove the excess nitric.
Later I added AR after the reaction died down i added smb for gold drop.
But now my solution is looking like this photo attached.
Can anyone explain me what the problem might be.
Thankyou in advance
Did you test for Gold with Stannous?Welcome to us.
This is a standard case of too little studies. And selection of non ideas processing.
Chips should not be processed with wet chemistry, it creates way too much waste.
Next you probably used premixead AR which is also wrong.
So now you have way too much Nitric, Nitrates and NOx in your mix.
You need to destroyed the Nitric with something, preferably not Urea.
But start studying first.
disolved in ar, filtered and all disolved my solution was dark greenish , added the SBR but it just fizzes and dissapears leaving me with no gold at all ??
awsome many thanks,If you mean C. M. Hoke's book, there are links in my signature line below.

so what is the best was to denox my soulution ??You did not mention de-NOxing your solution. If you still have free nitric in solution the SMB will drop the gold and the free nitric will re-dissolve any gold that was dropped. It will also generate the red fume as the metal is digested.
I think your solution still contains free nitric acid and that is your problem.
Best way is to not use too much Nitric, next best is to use Sulfamic acid.so what is the best was to denox my soulution ??
thanks

3parts mauriatic and 1 part nitric added slowly.Best way is to not use too much Nitric, next best is to use Sulfamic acid.
How do you make your AR?
That is your mistake, we never premix AR.3parts mauriatic and 1 part nitric added slowly.
Them I would cement it on Copper and refine it again.how much sulfamic should i use, solution was 150ml/50ml
how much sulfamic should i use ??Best way is to not use too much Nitric, next best is to use Sulfamic acid.
How do you make your AR?
Heat it to 90 Centigrade and add the Sulfamic slowly while stirring.how much sulfamic should i use ??
dilut with h20 or just add crystals to solution ??
thanks
I think that most people think of cementing out their gold with copper as something that you only want to do as a last resort.Them I would cement it on Copper and refine it again.
