well i have dissolved gold in the aqua regia I have magnesium ribbon and smb. I just put some parts of magnesium ribbon in the aqua regia. It start reaction and fizzing starts the beaker is going to be hot. Then i leave it for half hour i just put another some part of magneisum ribbon in the beaker again fizzing start after that i just put smb in the Aqua regia and again fizzing start brown fumes takeout from the beaker. But i didnn't see any participation of gold. Please help me i am struck here from the long time. I tried every thing. But fail what to do now. I just check the pins there is 35percent gold in every pins. Before aqua regia i did it will nitric acid to dissolved everything else gold and after that i didn't aqua regia. Please tell me where i am wrong.

If you still have NOx gas emitting when you are adding your smb you still have free nitric in solution.
You need to eliminate the excess nitric either by evaporation or the use of urea (not the favoured method on the forum, rather than using magnesium as you are adding extra metals into the mix which can report in your final product.

I think you should read Hoke
try this add water to the solution this will be better.....but answer the following before you do?
what is the total volume you have at the moment...?
take a pictures and post them too this will help with understanding what you are doing
have you tested the liquid for gold....?

Why are you adding magnesium ribbon to your ar? Put everything aside for now and start reading Hoke.
i am using magnesium ribbon to eliminate nitric acids and yes urea is not working for me there is a very low types of fizzing using urea. Should i put urea in liquid form because i have urea in grains form if i will put hot water in urea and dissolved urea in the water then should try ???????
Is there any good answer of my question or what every one saying reading hoke reading well obiviously we should read hoke book but this is the best forum if some one ask you something you should tell your practical experience with refining or your idea not reading hoke or something else. Ya i know there is gold dissolved in the aqua regia just tell me the best process of nitric acid eliminationg thanks .

Here we go again.
Reading Hoke is the best answer. It will explain how to do what you are attempting in a clear and concise manner. It will also give you all the background you need to understand why what you are doing is not working. It will really help you a lot if you start to understand what is happening and why. You begin to build a knowledge base of materials and their respective quirks and issues and how to avoid or solve them. Some one can tell you " Do this, this and this and your gold will drop. But you will make the same error next time and not know why. If you learn the "why did that happen" issues, you will be learning to recover and refine gold. Hoke covers most issues quite well for a beginner.

I suggest you check that "you owe me" attitude at the door before posting again.You were advised 3 times to read Hoke,before Glondor (nicely) broke it down,and explained it for you.We are not going to hold your hand and spoon feed you.If you follow directions now,it will make it easier for the rest of us to help you in the future.hciic said:

Hmmm! You're the guy that puts magnesium in what should be a gold chloride solution (to eliminate free nitric), yet you refuse to read Hoke?hciic said:
A little friendly advice. You don't know what the hell you're doing. If you did, there's no way you'd have introduced a reducing element to your solution to "eliminate" free nitric, for what you did is also very capable of cementing gold. If you'd read Hoke as you were advised, you'd know that. It was a monumental mistake. Get used to it.
Start reading Hoke, and don't come back until you understand what you are taught. If, then, you are still at a loss, maybe we can discuss this intelligently. Right now, that is not possible. You don't understand enough to be helped, and your attitude sucks. You were offered help, but it wasn't the help you sought---you waned a hand-out, not a hand-up. We don't do that here.
Be very careful in the words you choose if you respond to this post. I do not suffer fools gladly.

And I thought us American's, with our sense of entitlement, were bad.
You don't do any process by recipe, you do it by carefully observation, testing, dynamic decision making all based on knowledge you do not yet have. Hoke is the very basic minimum you need to even begin to understand the processes well enough, to be able to attempt any gold recovery or refining. What are you doing? Seriously, after you read Hoke you are going to do one or more of a few things. First, I suspect, if you read and understand Hoke, you are going to feel like a complete idiot for ever saying what you have thus far. Then you are either going to apologize for not reading it before and being pigheaded, or you might just disappear for good, out of embarrassment, or change your name and pretend you are new.
There is a saying that goes sort of like this. If you give a man a fish, he can eat for a day. If you show a man how to fish he will eat for a lifetime. You are asking us to give you fish, when you should be asking us where the fish are.
If you are smart enough to find this forum, then I have to believe you are smart enough to understand the value of listening to people who know more than you or I, and have suggested over and over through almost every thread, something about Hoke.

take some pictures and this will help people understand what you are doing..OK
and please read Hooks
do not add anything not even urea...OK
I will try to help but i dont want you to hurt yourself...your health is worth alot more then GOLD..lol

I just check these pins and got from the 1986 xray security machine. well one of my friend is in the laboratory and testing chemicals etc. I just give one pin to him to check how much gold in these pins he told me 40percent gold in the pin. He checked pin in the chemical laboratory using machine. First he told me to put these all pins in the nitric acid. I just put all the pins in the nitric acid 60ml as i think. The reaction was started and the brown fumes comes out from the beaker and then told me to put some more nitric acid to check if still brown fumes and reaction will work again i put 20ml in the solution. AGain reaction started when the reaction finished. we filtered all these pins and some kind of gold chopper and then i put all these pins in aqua regia 1 part of nitric acid and 3 parts of hcl. I put all these filtered pins etc in the aqua regia. When everything dissolved in the aqua regia. After one day I just put some magnesium ribbon . I see some where in the youtube video to put magnesium in aqua regia. The fizzing was started when i put the magnesium in the aqua regia and i put some magnesium and fizzing started. The beaker becomes hot when fizzing started using mag well after that when i see that not strong fizzing again putting another magnesium ribbon part i just put smb in the solution I see some brown mud then again dissapear after putting again i see again some brown mud and little fizzing and dissapear. Please tell me where i am wrong. After that i put 20ml distilled water in the solution then i heated with fire. And at the end all water etc evaporate with heating and i see some brown and grean mud in the beaker. If you need the picture i will also uploaded.

i think you should not have added the extra metal but that is what i think....and you might get a better answer from someone else.
instead of adding magnesium.....you can just add smb...
can you post a picture of the mud and i am going to ask you did you TEST the liquid...this is the magic word my friend....testing is everything..
to perfect the art of anything you must have testing in stages this tells you what is going on in the liquid...i use PH paper too.
Testing at set stages can explain what went wrong..and how to correct it for next time
pictures please and test the mud for gold...
to make a test if i am correct it is
15 mile HCL
2grams pure tin
you need to take a sample of the liquid and put a drop of the test on it look at the color of the better still take a picture...and post it

We can help you learn to do this, but it is not as easy as you make it sound, and as you are seeing now, we can help you learn but we cannot learn for you, you are the one who must study and work hard to learn.
You will need to study and study a lot; it will take time so you will also need to learn patience.
Hoke's book is the first book to read if you are seriously wanting to learn, also dealing with waste, and situations to avoid in the safety section, guide to the forum, an welcome members in general chat, and the forum in general, if you do this you will get an understanding of how to recover and refine the metals we discuss, it will take time, and will be a lot of work, but without doing this you might as well just give the solution you have now to your friend at the laboratory and give up trying to recover and refine gold and just , forget about getting gold with chemicals.
The pins in your picture, I do not believe are as rich in gold as the man at the laboratory says, did you remove plastic? I would have, the picture is blurry but it looks like some steel rings on pins in your picture, I would have removed these, they also look to have plastic pieces on them, did you incinerate them before using nitric? I would have this would have also removed the oils, I would not have added magnesium, to remove nitric from the aqua regia, I also would have not added as much nitric as you did, but added HCl and small additions of nitric and heat to dissolve the gold, this way it would be much easier to remove nitric acid, I would use the evaporation method to remove excess nitric acid evaporating down the solution to concentrate the nitric and gas it off, when solution is very concentrated add a small amount of HCl and repeat two more times, a small addition of gold would be another way I would have removed the nitric acid.
The magnesium precipitated other metals from your solution, and you must have not have removed them all with nitric before aqua regia, as if you have brown and green powders now.
Let all of the powders settle, remove liquid from them, test the liquid with stannous chloride, if you get a reaction for gold in solution, I would add a copper buss bar and cement out the gold, from solution, any powders from this, put these with powders you are saving (rinse these well and dry them), after all of the gold is out of solution add iron to the liquid stir it well, then neutralize solution with lime, let iron powder settle and remove clear salt water, dry the iron powder, you can read more about this in dealing with waste.
The jar of valuable powder mark this jar, and save them.
Now you should read Hoke's book there is a free download in the book section. The gold will wait for you to learn, but without learning you will just loose your gold.
