Chemical Dry Silver chloride-- Now What??

[Junior2021]

How was it made?
What is the base metals?
Do you need to keep the base metals untouched?
If not just dissolve the base metals in HCl or Nitric (Best).
And then reduce the AgCl with your preferred method.
NaOH/Syrup, Iron/Sulfuric or any other method.

NOTE: I had never been interested in refining silver, the price here in Brazil was very low, but I always saved the recovered Agcl residues, even when dirty, and I always kept them hydrated. Today I have about 6 kg of this residue. Now the price has gone up here in Brazil. Thank you, my friend Yggdrasil.

Thanks for your help
I have nitric and also hydrochloric, but the residue is this one. You can see that it is very dark, it even looks like it has already reduced, but it is not. It has copper, tin, and silver chloride together. I prefer to do the reduction with sodium hydroxide and glucose syrup. Thanks.

I have never dissolved AgCl in Ammonia.
What strenghts do you have?
The one most important thing is to reacidify immediately after precipitation.
The main issue I see in the current situation is the Tin.
First wash and filter as good as possible.
So after dissolving the AgCl, filter well again and add HCl or NaCl to it to drop the Silver as Chloride.
Wash this well and make sure all Ammonia is acidified.

Treat the now clean AgCl as your personal preference.

But let us wait a bit and see if someone has a better idea.

I usually restore such dirty chloride (sediment from the washing water from the stock pot) using aluminum and hydrochloric acid.
then I wash it with settling and decanting several times, then with caustic soda, after washing with clean water.
and dissolve everything with nitric acid.
