Silver/ gold mix

[Wonka]

If I melt sliver chloride if there’s gold in it will it stay at the bottom of the crucible?

If you melt silver chloride, somewhere around 850°F it melts and does not reduce to metallic silver. It is in its molten state any gold that was in the chlorides will be mixed in the bar you pour of solid silver chloride.

If you get too hot the silver chloride will begin to decompose and release its chlorine. It is a toxic choking gas. Don’t try to melt silver chloride to bring it to metal without proper fluxing, and even then it smokes considerably.

If you have reasonable amounts of gold in the mix convert the chloride to elemental silver redissolve in nitric and you have your gold separated and you can cement the silver to recover that.

Does this look right? I know you can’t see it in the picture but the solution is actually dark brown. It won’t settle either.

There it is

I started out with about 3000 ML of silver chloride added about 1 1/2 pounds of lime and several cups of sugar. It not acting normal.

Did you find any recommendations for using Lime?
NaOH/Lye/Sodium Hydroxide is what you should use.

Has it ever acted normal? You are using the wrong chemistry!

Sodium hydroxide converts Silver Chloride to Silver Oxide. Then the reduces the Silver Oxide to Silver metal.

The reaction, with the proper chemistry is self indicating with the caustic turning the clean white chlorides black. When the well stirred chlorides caustic mix is uniformly black, you start adding sugar (I prefer corn syrup) and keep mixing. You will see the black Silver Oxide turn to Gray metal when you add enough to reduce the Silver Oxide to metal. Again seeing the gray emerge with no black streaks means you are done.

I meant lye. It was a autocorrect error

Turn off autocorrect. It makes more mistakes than you.

What acid does not dissolve silver? And how fast will sulfuric acid dissolve it?

Your questions indicate you haven't studied much.
Are you planning to replace Nitric with Sulfuric?

No, I have the silver made. I just wanna clean it up a bit. Incase there’s impurities.

Well no person makes Silver or any other element.
How did you prepare your Silver?
