View Full Version : Dissolved gold precipitation?

I have previously posted some info on my dissolving gold with home made nitric acid.

No problem people...it must be nitric acid as all the gold has gone now.
I guess the salt must have supplied the chlorine...which was what I was hoping for as I had no HCl.

It seems strange having liquid gold in a glass :)


Then I read an article by Vlad and a link to making ormus.

heres a point

I saw that you needed to take the gold in solution from acid to alkali and back several times
to break the bonds in the gold...or so it said :)

I did this with my dissolved gold using a solution of lye and some nitric acid.

A strange thing happened while doing this and I will tell you more when I get home from work.

For now you can see the precipitate (http://genius.toucansurf.com/gold precipitate.jpg) that formed as a result of me doing the above procedure. And another angle. (http://genius.toucansurf.com/gold precipitate2.jpg )

When lye was added, the solution turned red...
the precipitate started to fall out.

The p.h. was checked with litmus paper so it was only a rough estimate.

Adding the nitric turned the solution back to yellow.

At one point and one point only the solution seemed to bubble,
what looked like oil, on the surface. Would anyone be able to shed some light on this?

I am going to repeat what I did, but this time I will capture
it all on vid so you can see what happens.

Some gold has already been dissolved for this purpose. This time however
instead of using nitric with a little common salt, proper aqua regia was
used using nitric plus HCl.

you may want to look at this. steps 11 and 12 produce a gold nitrate.
It's pretty cool if adding lye gave you a red!

I am only doing this on a microscopic scale...I dont think I can take it much
further at the moment due to a lack of materials. I made a vid of a second
attempt...the colours were not so obvious as the first but I think you can still see

The vid will open as soon as you click here (http://genius.toucansurf.com/precipitate movie.wmv).
Be aware the movie is a little long winded and a bit small to upload it quicker :o

Where do I go from here?
