Washing pure silver powder

[goldsilverpro]

amesametrita,

I did discuss it before. I have held nothing back on the forum, with only 1 or 2 exceptions. The reason for holding those back was due to agreements I made many years ago. What's your excuse?

There may be a couple more here.

I told Lou about it and he experimented with it.

Unfortunately you haven't discovered the method.
It's almost industry standard for high purity wet method.

Are you saying that the use of EDTA to actually PRECIPITATE the gold is industry standard? I'm not talking about just tying up the base metals. That is fairly standard. I'm talking about actually precipitating the gold with it. I developed the method in about 1969. I've never seen a reference to it in the literature, then or now, and I've always searched and read everything I could find about processing Au/Ag scrap. I would have noticed. Perhaps you could supply me with a reference, preferably written before 1969. Anything after that could be a leak from someone in the company I worked for or from Dow. When I was working with it back then, I discussed it with chemists at Dow Chemical, the primary manufacturer. They knew nothing about using it for dropping gold.

I'm really sorry I blamed you for hiding this method.
Next time will use search button.
I can't comment it myself because we don't dissolve gold in production.
Just parting to get Au.995+(Au+Ag.9995+)
As I already said it is economically unfeasible to go higher in our case.
But all my friends in Arrezo, Italy drop gold with fancy organic, including EDTA
It looks amazing!

What's your excuse?

I don't hide any theoretical info.
I just can't identify myself as I already said.
I can simply loose my job then.
Let's say we refine more than 100toz of gold a day and much more than 1000toz of silver a day.

So now we've both apologized. I for the silver cell and you for the EDTA. So, what do you say we both stop our pi**ing contest. Let's get back to the forum motto as Noxx has stated on the first page, "Gold refiners helping one another, worldwide!"

Of course, I can understand your position and the last thing I would want is for you to lose your job. You can talk theory but not specific setups. Explains a lot. I now see why you're doing things by PM.

Welcome to the forum! I mean that.

I washed it only with distilled water many times. In the video it looks white my silver looks like cat litter
But the results speak for themselves. I had tried the copper method but I was precipating the palladium along with the silver and it was very slow. Anyway thanks for the sound advice. It worked very well.

Thread got a bit heated here, Anyway I think all the 'pros' here keep a 'killer process' of their own doing a secret, especially if their doing it for competitive edge as in business. Just like KFC has it secret 11 herbs and spices. A web forum that offer free information should be thought of as for 'the hobbist' whereas professionals following industry standard would likely not be a part of. Hoke's book although dated has great information and processes that work, but at some point someone will eventually invent a process to do something a few minutes faster, with a little less water or less waste. Example I didn't know EDTA dropped gold, but did know it clean up waste gold well back when I dropped gold with copper! I gotten fallout when I first advised acetone to drop gold. Anyways the great wonder of the internet is, that to find this refining information say back in the 1980's would have had you to travel to DC to the library of congress or have permission to a univerisity library and search books and microfiche and you probably came across Hoke's book having you to make Xerox copies and notes, and being pre-eBay how could you have got your hands on HNO3 or SMB?

Looks good, just like Apmex shots.

I think for the most part, like butcher, geo, howard,gsp,lou,steve, noxx, (and the list goes on forever) not to mention all the others that take the time out to hear the same questions over and over and still show great patience, are concerned more about the saftey of those that are trying to figure things out. The reasons for this are not only honorable, but commendable and necessary for the safety of others on this forum. Most of us don't have a clue what you are talking about. A lot of people usually take it upon themselves to try to figure it out without going through the necessary steps required for our safety or do we want to spend the time searching the forum for whatever we need to know for hours on end. So long story short. It is a lot better to keep all this in mind and ask yourself if this info. could cause conflict/safety issues/confusion etc. to anyone on this site and even if there might be the slightest chance of anything of this nature use the pm feature.I hope you understand and know that everyone here is helping in whatever way they can and this is the only site that strictly holds to those standards. That's why you will only find some of the greatest minds in the industry right here. So welcome to our forum and I always love to see a discrepancy worked out as long as these guidelines are followed. Safety First.
