Hey my smileys turned to numbers
nitric acid has been around for thousands of years and that is how they refined precious metals....mercury will attach to silver but it will not purify it...lime and borax are flux's used in smelting
i still don't think you are getting this....you don't refine silver in the smelting process....you refine it with nitric acid after the smelt...very simple process...if you tried to use nitric in the smelting process something real bad might happenAzdave
It seems Nitric Acid was invented in 1647, that falls way short of thousands of years. Now it seems to be the things I picked have been around for thousands of years. Such as Mercury borax lime and cinnabar. Mmm[emoji3]
But using nitric acids is nothing more then a oxidizer,
Witch means in the lay mans terms in nothing more then a bellows. Forced air into the mix, is a oxidizer.
So the mine of chalky stuff was used as a flux, and a bellows applied the oxidation.
So pretty much of your smelting advice was not to correct.

AZ Dave, you posted ---- a bead of precious metal which is measured or weighed to tell how many opt (ounce per ton)
"You then have to seselectivly separate the metal content then weigh each individually. A 3 (gpt)Gold bead is mighty small,you handle it with the point of a needle. but it is the result of a typical gold mine today..
I used to scrounge all of the dead cattle nearby to use their bones for my cupels, at times of need, mixed up to 1/3 with previously tested cement.![]()
Hola Dave, how many 1 oz mines have you seen lately>>generally grams / ton I enjoy your posts
my friend.
I used a standard balance and a kahn electornic balance. Now you can go to harbor Freight and get a lil elecronic balance for around $ 20 . sigh.
That old standard Balance is sitting in the bookshelf just across the room. The Dove likes to cozy up to it.
Is there a smelter location on the stone maps I don't know about?
az, I agree with the torch assay for an in the ball park assay.. The trouble I had when assaying was to get a relaively round bead, they always were slightly irregular. but for the small miner adequate.
