I have heard the mining term to charge mercury, dirty mercury can be "charged" or cleaned (distilled) in retort. Sometimes triple distilled.

As we have all said forget the mercury, it is too dangerous, it will not work that great, and there are much better methods.

Give us better description of your gold.

Where the gold it came from.

What treatments has it gone through?

Describe it and how you have proven it to be gold.

We can give you some advice on recover methods if we have some idea of what we are discussing.


From what I understand you are working with fine screened concentrates in black sand (it will not be 24K gold, usually 16 to 18K). It sounds to me you would need a leach, but until we know more details, I will not give advice, because of what you may have up until this point (the advice can be dangerous, if we do not know what you have).

It is very important for you to tell us if this gold has come into contact with your mercury, as suggestions and your safety would depend on these facts.

From what I understand you have mercury that came from a hospital, please put it in good jar with good air tight lid, cover mercury with water(to keep from evaporating into the air), sit this in another plastic tub with lid in a safe place, forget about trying to use mercury to recover for gold. As we said that would be a very bad idea.

Here the mining supply store sells mercury, but I think most people buying it must not know enough about it, to get there gold, or the dangers of this stuff, luckily they also sell retorts, and hopefully they are not poisoning themselves, or driving themselves crazy, (Madd as a Hatter).
 
No need to use mercury at all. It is far safer to put all your cons in one place. When you have sufficient quantity, smelt them. You will end up with a pretty yellow button consisting of mostly gold. You might get ahold of Megan Rose on the GPAA forum. She has more knowledge on gold recovery from placer cons than I do.
 
Actually – yes you can “charge” mercury by adding ether sodium or potassium to it. It becomes like mercury on Viagra in its ability to amalgam with gold. This can be done in an electrolytic cell

However – if you are having a problem with un-charged mercury picking up your gold – charging it is not going to fix the problem because you already have some other problem existing that is preventing the “natural” process of mercury to amalgam with the gold.

Ether your mercury is contaminated, or your gold is contaminated, or both.

Jojo – you now have a “REAL” problem on your hands!!! Why? --- Because you have already tried using mercury on the material you have – therefore you have now contaminated that material with mercury & the “ONLY” safe way to remove the mercury is with a retort – which is something you “NEED” to have anyway if you are going to use mercury to recover gold by way of amalgam process --- & I am betting that you don’t have a retort.

So – what I would suggest – is that you take the material you have – to a professional refiner – tell them about the mercury contamination so they are informed & apply the proper safe process to dealing with the mercury in recovering your gold.

Giving you any other advice (outside of using a retort to deal with the mercury) would be nothing short of telling you how to poison your self with mercury poisoning --- & I am not going to help you with that & I doubt anyone else on this forum will help you poison your self ether. (which is why I am not giving detailed instruction on how to “charge” mercury)

the mercury is from old hospital equipment....

the gold has been put in nitric acid and is sitting with whatever other metals in water (come from washing PC motherboards with acid)

What other reasons would the gold not stick to it...

It may have soap or oil on it yes, but can I "charge" the mercury and get a better reaction than with just pure mercury rolling around with gold, because I'm seeing no action....


....

I understand the hazards but am just wondering, what activating hazards should I do to start off, the rest is all done by the book, no dumping and washing into water supplies..

There is a reason I still have the mercury, because I know some idiots. Im trying to do it the right way, I just do not know it

At least the beginning..I know how to finish it up and try to save it. Know it requires more $, just do not know how much
 
jojothebarbarian,

I do not know how to get you to understand.

If you had gold in contact with mercury, your gold is now contaminated, and very dangerous to work with, you will need to have it retorted (distilled), if you have not done this then take it to a professional and have it done.

I will not help with using mercury, it is not needed, it will not work that great, and is far too dangerous (if not done properly).

If your gold is clean of mercury we can help you with methods of recovery and purification.

sorry I am not trying to be difficult, and would like to help, (but I will not help you use mercury).
 
Jojothebarbarian you wrote – “the gold has been put in nitric acid and is sitting with whatever other metals in water (come from washing PC motherboards with acid)

This is where your problem is - Because you used acid to wash (or strip) your mother boards you created a situation where all the other stuff that your gold is now mixed in with is contaminating the mercury & therefore preventing the mercury from picking up the gold.

When you used the nitric to strip the gold plating from your mother boards the nitric also made a tin paste from the solder & a whole bunch other metals that are now in the form of metal salts &/or oxides.

These things are contaminating your mercury as soon as you put the mercury in with it & because all this other stuff contaminates your mercury as soon as you put it in – it prevents the mercury from picking up the gold.

Charging the mercury IS NOT GOING TO FIX THE PROBLEM (I am not yelling here – just trying to get you to understand that using mercury in this situation is not going to work for you – no matter what you do with the mercury) Charging the mercury is only going to make the mercury better at contaminating it’s self with all this other stuff .

Another words – the problem is not the mercury &/or the gold --- it is the stuff that the gold is mixed with.

The ONLY way you are going to get your gold from this stuff – is to use AR (aqua regia) to dissolve the gold & then ether precipitate the gold back out of solution using SMB or cement it back out of solution using copper

So – now – if you need help with the AR/SMB process --- or the AR/copper cementing process – we can certainly help you with that

What possible reason can you have to use mercury in this case? What do you expect to accomplish?

Edit: I get the distinct impression you have been reading too many comic books, and you don't have a clue about refining. Mercury is NOT a refining procedure. At best, it is a recovery procedure, one that is not the least bit necessary for processing escrap.
Have you read Hoke?
 
He still cant understand one thing. Mercury was used to accumulate gold which is so small that is barely visible with naked eye. Anything bigger will just get coated with mercury - contaminated.
 
I believe I remember reading that "charging" mercury was using electrolysis to produce a sodium-mercury amalgam (liquid alloy). As a reducing agent the sodium in the mercury would keep the surface of the mercury clean during panning, allowing it to more easily stick to gold particles.

Like just about everyone else here I would recommend not using mercury in the first place.

Over 50 years ago, my father took me to a place where there was a huge wooden box, filled with dirt, rocks, water and supposedly gold flakes. I remember panning some of it, and was told that my glittery stuff was gold. They put it in a small bottle with mercury. Needless to say, I found the bottle about a month ago and was wondering what to do with it, and found this post. I really don't want to mess with the mercury, so.......how do I get rid of it? Someone, I have no idea who, told me to put all of it in a potato and squeeze the mercury out, and it will leave the gold in the potato. Still, if I did that, what do I do with the mercury? Any ideas or comments would be appreciated.
 
When I lived on Long Island, the town I lived in had a STOP Saturday, stop throwing out pollutants. It was once a month and it assured common pollutants were disposed of properly. It was free to residents.

If you had this service available, the solution is simple. Pour the mercury and gold through a chamois cloth, the gold will remain in the cloth which can be squeezed out to separate most of the mercury from the gold. The gold is not pure but it is separated from the majority of the mercury and you can get an idea of how much you have. Then clearly label the jar with the mercury you just filtered out and place the gloves you wore and the chamois cloth in there and label it mercury contaminated materials. Drop the jar off at the STOP drop off center and let us know how you made out.

If there is sufficient gold after removing the mercury (I doubt there will be, those panning businesses were set up to make money, not give it to the panners) I'm sure some members can help you get it pure if you so desire.

I think the real purpose of the mercury was to disguise how little actual gold was there and have you think you were actually going home with something of value.
 
Thank you for your reply, you are probably correct in that there will be little gold in this vial. Will let you know how it turns out when I try the chamois squeeze. Currently having to stay away from my processing endeavors due to a case of pneumonia.
 
Hi Kurt

I'm using spent mercury to collect my near-colloidal gold. How do you charge the mercury using potassium + electrolysis ? what's the elcetrode to be use ? ratio of K and Hg ? amps & mV ? any advice ?

mercury is so very poisonous that it will be hard to find someone to help with its use when there are so many other BETTER processes to recover gold.i wish this thread had never been started in a way because at this time when gold is bringing such a high price people seem to be willing to throw safety to the wind (literally).in my opinion this topic is much more dangerous than the other dangerous topic that had divided the forum so fiercely.everyone has heard about the old miners using mercury to get the gold so heres a tip: MERCURY DOESNT WORK TO RECLAIM GOLD FROM ELECTRONIC SCRAP, it was used in mining and prospecting.mercury will not collect gold from electronics.
 
Thanks Geo,
very well put, I agree with you 99.999%.

I will go so far as to say mercury for mining gold is also outdated, and no longer needed.

I do not think the forum has been devided over issues of safety, yes we may see some things differently, but we would not be individuals if we did not, I believe all of us are on the same page on the forum, want to get our metals as safely as possible, and help others to get theirs safely, and we all want information to be as free as possible, and for others who may read this forum to use that information intelligently.
 
Geo, you posted ---"MERCURY DOESNT WORK TO RECLAIM GOLD FROM ELECTRONIC SCRAP"

Actually that’s not true --- but first let me say – IN NO WAY AM I ADVOCATING THE USE OF MERCURY (caps fore emphasis – not yelling)

Mercury works “very” well for recovering the gold wires from the ash of incinerated IC chips. It works just as good in this case as it works for recovering fine gold from black sands &/or crushed ore. --- That said – the fact remains that using mercury is still a very hazardous method to recover gold. --- If you do not have the proper lab &/or equipment set up – if you are not VERY careful when handling it – if you do not have a FULL knowledge & understanding about working with mercury --- you are IN FACT setting your self, your friends & your neighbors up for VERY SERIOUS health risk including a “very slow & agonizing death”

YOU WONT EVEN KNOW ITS HAPPENING TO YOU UNTILL ITS TO LATE (again caps used of emphasis – not yelling) let me say that again

YOU WONT EVEN KNOW ITS HAPPENING TO YOU UNTILL ITS TO LATE

One more thing --- mercury “will not” work for recovering gold foils --- not even if you charge it. There are three reasons for this – I am not going to go into those reasons, I am simply going to say it one more time --- mercury “will not” work for recovering gold foils --- not even if you charge it… (That’s three periods at the end of that sentence)

Kurt,
I do not think that mercury will work well to pick up wires from incinerated ic packages. There is simply too much of small pieces of other metals mixed in lot and most of them are gold plated at least on tip where wire was soldered in. There is no way that mercury will take in gold and not these pieces of metal, it will be smeared on them. I do not think that it is fail safe method for collecting fines. Nitric leach or AR are far better options than introducing mercury. It may work in some degree to collect very fine small particles which can be collected or recovered another way - safer and all of them.
 
Pat – you are right – it is not as simple as incinerating the chips – crushing them - & putting mercury in the ash to recover the gold wires.

There are steps that “need” to be taken prior to introducing the mercury in order for the mercury to be effective in picking up the wire. – If these step are not taken prior to introducing the mercury you will have poor success at recovering the gold. --- In fact – if not done right – you will end up with ash contaminated with mercury & little or no recovered gold.

Mercury IS NOT the “magic” answer to gold recovery. --- In order for mercury to be effective to amalgam with the gold the conditions need to be ideal.

Contamination is a problem - & contamination can be a problem in any of three places (1) if the mercury is contaminated it will NOT be effective (2) if the gold has a surface contamination it will NOT be effective (3) if the media you are trying to recover the gold from has contaminates (that ether contaminate the mercury &/or the gold) it will NOT be effective.

These things are a matter of FACT with both natural sources (placer concentrates &/or crushed ore concentrates) or gold from electronics. --- In FACT contamination in electronics is a “major” problem.

So --- my POINT is that – yes – as much as mercury can be used to recover gold --- it IS NOT the “magic” answer to gold recovery & this is especially true with trying to us it to recover gold from electronics --- you actually “create” contaminates in the process of getting the gold to a point that it can be recovered. – Therefore -----

Due to the nasty nature of mercury I will not discuss this further here on the forum. (other then to discourage the use of it)

Kurt

With the idea in mind that we sound as if we actually know what we're talking about, the phrase, above, one does not create "contaminates", but contaminants. The contaminants contaminate the material.

I saw producing process of virgin mercury. It is relative safe for worker, but it pollute environment badly.
