Gold parting - Wikipedia

Gold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum. With ...

Reasons for the Lydian electrum coins and the succeeding Greek silver coins in antiquity VOX, CEPR Policy Portal

Electrum is an alloy of gold and silver that varies in its natural state between 65% and 85% gold, and neither weighing nor the touchstone can tell the percentage in between with any precision. Therefore, the metal would seem to be a particularly poor choice for coinage, and it was widely considered so until recent decades.
