How to separate silver from gold ore>

was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold.

PARTING: Separate Gold and Silver by Melting

In this ancient and obsolete process, gold was freed from small quantities of silver, copper, &c., contained in it. The method was mentioned by Pliny and described by Geber, who wrote in Arabic, probably in the eighth or ninth century; it is possibly still in use in some parts of the East and of South America.

50% gold mixture isn't a problem to melt directly, that's enough to separate and get the gold to melt together. But from your description I'm not totally convinced that you actually have gold. Pyrite and mica is often mistaken for gold and is a lot harder to separate, but if it melts together into a metallic blob then it was probably gold. Göran

I don't think you can always use melting points, because alloys, depending on the composition (looking at phase curves) can have one common melting point. Here's a phase diagram for a copper-nickel alloy, which I think is a system where both components are completely soluble in one another in all ratios.
